3 Description

The TPL5010-Q1 Nano Timer is a low power, AEC-Q100 qualified timer with a watchdog feature ideal for system wake up in duty cycled or battery powered applications. In such systems, the microcontroller timer can be used for system wake-up, but if the timer sleep current is high, up to 60-80% of the total system current can be consumed by the microcontroller timer in this sleep mode. Consuming only 35 nA, the TPL5010-Q1 can replace the functionality of the integrated microcontroller timer and allow the microcontroller to be placed in a much lower power mode. Such power savings extend the operating life of batteries and enable the use of significantly smaller batteries, making the TPL5010-Q1 ideal for power sensitive applications. The TPL5010-Q1 provides selectable timing intervals from 100 ms to 7200 s and is designed for interrupt-driven applications. Some standards (such as EN50271) require implementation of a watchdog for safety, and the TPL5010-Q1 realizes this watchdog function at almost no additional power consumption. The TPL5010-Q1 is available in a 6-pin SOT23 package.

8 Detailed Description

8.1 Overview

The TPL5010-Q1 is a system wakeup timer with a watchdog feature, ideal for low power applications. The TPL5010-Q1 is ideal for use in interrupt-driven applications and provides selectable timing from 100 ms to 7200 s.

8.2 Functional Block Diagram

The functional block diagram shows the internal components: a Low Frequency Oscillator, a Frequency Divider, a Decoder & Manual Reset Detector, and Logic Control. These blocks are interconnected, with inputs from VDD and DELAY/M_RST, and outputs to RSTn, WAKE, and DONE, all referenced to GND.

8.3 Feature Description

The DONE, WAKE, and RSTn signals are used to implement the watchdog function. The TPL5010-Q1 is programmed to issue a periodic WAKE pulse to a µC which is in sleep or standby mode. After receiving the WAKE pulse, the µC must issue a DONE signal to the TPL5010-Q1 at least 20 ms before the rising edge of the next WAKE pulse. If the DONE signal is not asserted, the TPL5010-Q1 asserts the RSTn signal to reset the µC. A manual reset function is realized by momentarily pulling the DELAY/M_RST pin to VDD.

8.3.1 WAKE

The WAKE pulse is sent out from the TPL5010-Q1 when the programmed time interval starts (except at the beginning of the first cycle or if in the previous interval the DONE has not been received). This signal is normally low.

8.3.2 DONE

The DONE pin is driven by a µC to signal successful processing of the WAKE signal. The TPL5010-Q1 recognizes a valid DONE signal as a low-to-high transition. If two or more DONE signals are received within the time interval, only the first DONE signal is processed. The DONE signal resets the counter of the watchdog only. If the DONE signal is received when the WAKE is still high, the WAKE will go low as soon as the DONE is recognized.

8.3.3 RSTn

To implement the reset interface between the TPL5010-Q1 and the µC, a pull-up resistance is required. 100 kΩ is recommended to minimize current. During the POR and the reading of the R_EXT, the RSTn signal is LOW. RSTn is asserted (LOW) for either one of the following conditions: 1. If the DELAY/M_RST pin is high for at least two consecutive cycles of the internal oscillator (approximately 20 ms). 2. At the beginning of a new time interval if DONE is not received at least 20 ms before the next WAKE rising edge (see Figure 8).

8.4 Device Functional Modes

8.4.1 Startup

During startup, after POR, the TPL5010-Q1 executes a one-time measurement of the resistance attached to the DELAY/M_RST pin to determine the desired time interval for WAKE. This measurement interval is t_{R_EXT}. During this measurement, a constant current is temporarily flowing into R_EXT.

Startup Timing Diagram: Shows WAKE, DONE, RSTn, and DELAY/M_RST signals during startup, including POR, resistance reading (t_{R_EXT}), and the subsequent timing.

8.4.2 Normal Operating Mode

During normal operating mode, the TPL5010-Q1 asserts periodic WAKE pulses in response to valid DONE pulses from the µC. If either a manual reset is applied (logic HIGH on DELAY/M_RST pin) or the µC does not issue a DONE pulse within the required time, the TPL5010-Q1 asserts the RSTn signal to the µC and restarts its internal counters. See Figure 8 and Figure 10.

8.5 Programming

8.5.1 Configuring the WAKE Interval with the DELAY/M_RST Pin

The time interval between 2 adjacent WAKE pulses (rising edges) is selectable through an external resistance (R_EXT) between the DELAY/M_RST pin and ground. The value of the resistance R_EXT is converted one time after POR. The allowable range of R_EXT is 500 Ω to 170 kΩ. At least a 1% precision resistance is recommended. See Timer Interval Selection Using External Resistance for how to set the WAKE pulse interval using R_EXT. The time between 2 adjacent RESET signals (falling edges) or between a RESET (falling edge) and a WAKE (rising edge) is given by the sum of the programmed time interval and the t_RSTn (reset pulse width).

8.5.2 Manual Reset

If VDD is connected to the DELAY/M_RST pin, the TPL5010-Q1 recognizes this as a manual reset condition. In this case, the time interval is not set. If the manual reset is asserted during the POR or during the reading procedure, the reading procedure is aborted and is re-started as soon as the manual reset switch is released. A pulse on the DELAY/M_RST pin is recognized as a valid manual reset only if it lasts at least 20 ms (observation time is 30 ms). A valid manual reset resets all the counters inside the TPL5010-Q1. The counters restart only when the high digital voltage at DELAY/M_RST is removed and the next t_RSTn is elapsed.

Manual Reset Timing Diagram: Illustrates WAKE, DONE, RSTn, and DELAY/M_RST signals during manual reset, showing valid and invalid manual reset pulses and their effect on RSTn.

8.5.2.1 DELAY/M_RST

A resistance in the range between 500 Ω and 170 kΩ needs to be connected to select a valid time interval. At the POR and during the reading of the resistance, the DELAY/M_RST is connected to an analog signal chain through a mux. After the reading of the resistance, the analog circuit is switched off, and the DELAY/RST is connected to a digital circuit. The manual reset detection is supported with a de-bounce feature, which makes the TPL5010-Q1 insensitive to glitches on the DELAY/M_RST pin. When a valid manual reset signal is asserted on the DELAY/M_RST pin, the RSTn signal is asserted LOW after a delay of t_{M_RST}. It remains LOW after a valid manual reset is asserted + t_DB + t_RSTn. Due to the asynchronous nature of the manual reset signal and its arbitrary duration, the LOW status of the RSTn signal may be affected by an uncertainty of about ±5 ms. A valid manual reset puts all the digital output signals at their default values: WAKE = LOW, RSTn = asserted LOW.

8.5.2.2 Circuitry

The manual reset may be implemented using a switch (momentary mechanical action). The TPL5010-Q1 offers 2 possible approaches according to the power consumption constraints of the application.

8.5.3 Timer Interval Selection Using External Resistance

In order to set the time interval, the external resistance R_EXT is selected according to the following formula:

R_EXT = 100 √[ –b + √(b² – 4a(c – 100T)) / 2a ]

where:

T is the desired time interval in seconds
R_EXT is the resistance value to use in Ω
a, b, c are coefficients depending on the range of the time interval

Table 2 lists the coefficients for Equation 1 based on the time interval range.

Example: For a required time interval of 8 s, coefficient set 2 is used, resulting in R_EXT = 10.18 kΩ.

Tables 3 and 4 provide example values of t_IP and their corresponding R_EXT values, including closest real values and parallel combinations of 1% tolerance resistors.

8.5.4 Quantization Error

The TPL5010-Q1 can generate 1650 discrete timer intervals from 100 ms to 7200 s. The first 9 intervals are multiples of 100 ms, while the remaining 1641 intervals cover 1 s to 7200 s. Quantization error is associated with these discrete intervals and can be evaluated using the provided formulas.

8.5.5 Error Due to Real External Resistance

Since theoretical R_EXT values may not be standard, using parallel resistor combinations is common. Standard resistor tolerances affect time interval accuracy. The accuracy can be evaluated by calculating min/max R_EXT values, then the corresponding time intervals (T_{ADC_MIN}, T_{ADC_MAX}), and finally the error using the provided formulas.

Example calculation shows how to determine the uncertainty of an equivalent parallel resistance and its impact on the time interval accuracy.

9 Application and Implementation

NOTE: Information in the following application sections is not part of the TI component specification. TI customers are responsible for determining suitability of components for their purposes and should validate and test their design implementation to confirm system functionality.

9.1 Application Information

In battery-powered applications, low current consumption is a key constraint. The TPL5010-Q1 is ideal for applications needing to monitor environmental conditions at fixed time intervals. It can replace microcontroller timers for wake-up functions, consuming only tens of nA, significantly improving system power consumption.

9.2 Typical Application

The TPL5010-Q1 can be used with environment sensors to create low-power data loggers, such as air quality loggers. In these applications, the microcontroller and sensor front end often remain in an idle state, waiting for the next logging interval. Figure 13 illustrates a data logging application using a µC and a gas sensor (LMP91000).

Figure 13: Data-Logger Diagram: A system diagram shows a lithium-ion battery, power management, TPL5010-Q1 timer, a microcontroller (µC), voltage reference, and a gas sensor (LMP91000). It includes connections for R_EXT, pull-up resistors, and communication interfaces, as well as a display and keyboard.

9.2.1 Design Requirements

The primary design driver is low current consumption to maximize battery life. Data acquisition rates typically range from 1 s to 10 s. The TPL5010-Q1 facilitates this by enabling the µC to operate in its lowest power mode, while the TPL5010-Q1 manages watchdog and timing functions.

9.2.2 Detailed Design Procedure

When battery life is critical, selecting a low-power voltage reference, µC, and display is essential. The first step is calculating power consumption for each device mode. For example, the LMP91000 consumes most power during gas measurement, with idle states (stand-by, deep sleep) for other times. Similarly, µCs like the MSP430 family can enter low-power modes. The TPL5010-Q1 can implement watchdog and wake-up timing in these scenarios. After power budget calculation, the appropriate time interval can be selected to meet application constraints and maximize battery life.

9.2.3 Application Curves

Figure 14: Effect of TPL5010-Q1 on Current Consumption: A graph comparing current consumption over time, showing that using the TPL5010-Q1 significantly reduces the baseline current consumption compared to a system without it.

10 Power Supply Recommendations

The TPL5010-Q1 requires a voltage supply between 1.8 V and 5.5 V. A multilayer ceramic bypass X7R capacitor of 0.1 µF between VDD and GND pins is recommended.

11 Layout

11.1 Layout Guidelines

The DELAY/M_RST pin is sensitive to parasitic capacitance. Traces connecting this pin to ground for resistance measurements should be kept as short as possible to minimize capacitance, which can affect time interval setup. Signal integrity on WAKE and RSTn pins is also improved by keeping trace lengths short between the TPL5010-Q1 and the µC.

11.2 Layout Example

Figure 15: Layout Diagram: A PCB layout example shows the placement of the TPL5010-Q1, a manual reset switch, capacitor C1, external resistor R_EXT, and pull-up resistor RP, along with routing to a microcontroller and ground plane.
