Introduction
The STEVAL-L9800 is a tool designed to evaluate the L9800 smart power device, designed by STMicroelectronics in advanced BCD technology. The L9800 is an 8-channel IC with eight LS drivers designed for automotive applications (LEDs and relays) and compatible with resistive, inductive, and capacitive loads. The device offers advanced diagnostic and protection functionalities such as short to GND, open load, overcurrent, and overtemperature detection. The 8 output channels can be driven by SPI or by 2 dedicated parallel inputs that can be associated to different output thanks to a programmable internal multiplexer. Limp home functionality is also featured, which allows the use of 2 selected drivers in specific fault conditions, such as SPI fault, microcontroller fault, or supply UV. Daisy chain compatibility even with 8-bit SPI is available. The device is able to ensure operation in cranking scenarios down to VBATT = 3 V and very low quiescent current in the SLEEP condition. A serial peripheral interface (SPI) is used for control and configuration of the loads and the device. Status feedback of all diagnostic functions is also provided. There are two input pins available for direct control and PWM: these are connected to two defined outputs by default, but additional or different output mapping can be controlled by SPI. Thanks to the expansion connectors, the STEVAL-L9800 allows the complete control of L9800 communication interface (SPI) and parallel input/output. The evaluation platform may also be controlled through a graphical user interface (GUI) on the AEK-MCU-C1MLIT1 hardware interface.

3.1

Minimum setup

In order to operate the STEVAL-L9800, the following equipment is necessary:

VBATT power supply 3 – 28 V current capability up to 8 A

VDDIO power supply 3 – 5 V (only if AEK-MCU-C1MLIT1 is not used)

Loads: LED, relay, lamp with a rating of 12 V, 0.5 A

Optional: AEK-MCU-C1MLIT1 and STEVAL-L9800 GUI

For AEK-MCU-C1MLIT1 board usage, please refer to the relevant user manual.

3.2

Startup

Follow the steps below before using the board, :

Step 1. Configure the power supply to desired voltage level and limit the current to n x 1 A where n is the number of connected loads.

Step 2.

Switch power supplies on and check that VBATT LED and VDDIO LED are switched on (if the VDDIO pin is supplied by the AEK-MCU-C1MLIT1 board, the VDDIO LED will switch on when USB cable is plugged into the PC).

Step 3. Control IDLE input and SPI settings according to the L9800 datasheet.

Step 4. Check IN0 and IN1 according to your setup.

Step 5. Check that the output LEDs switch on correctly when the associated output is switched on.

3.3

Usage example

In this section, a usage example is described, according to the configuration provided in the following table.

Channel CH0 CH1 CH2 CH3 CH4 CH5 CH6 CH7

Table 3. Example configuration

Configuration Solenoid actuator Main Relay LED Resistive Load Relay Bulb lamp (unconnected) (shorted to GND)

Load IN0 SPI LED PWM generator GEN PWM generator SPI IN1 SPI SPI

Startup phase:

Step 1.

Power up the system
With the load configuration given in Table 3, if J25 (LEDs jumper) is closed, the output LED of CH7 will switch on since drain 7 is shorted to GND.

Step 2. IN0 = 0, IN1 = 0, IDLE = 0. The device is in sleep mode

Step 3. IN0 = 0, IN1 = 0, IDLE = 1. The device is in idle mode

Step 4.
Step 5. Step 6. Step 7.

SPI initial configuration:
MAP_IN0: 0x9C04 (associate IN0 to CH0, frame counter = 0) MAP_IN1: 0xA081 (associate IN1 to CH5, frame counter = 1) CFG_1: 0x8802 (LED PWM generator freq = 122.5 Hz, frame counter = 0) CFG_2: 0x8C01 (GEN PWM generator freq = 122.5 Hz, no adjustment, frame counter = 1) PWM_LED_DC: 0xB000 (PWM LED duty cycle = 0%, frame counter = 0) PWM_GEN_DC: 0xAC03 (PWM GEN duty cycle = 0%, frame counter = 1) MAP_PWM: 0xA430 (CH2-CH3 driven by internal PWM generators, frame counter = 0) PWM_SEL: 0xA813 (CH2 driven by PWM LED & CH3 driven by PWM GEN, frame counter = 1) BIM: 0x9080 (activate bulb inrush mode on CH5, Frame counter = 0) CFG_1: 0x8901 (put device in active mode, frame counter = 1) STA_1:0x4402 (read Status register 1, expected results POR = 1, VDD_UV = 0, VS_UV = 0
MODE = 11: active mode, frame counter = 0)
The implemented SPI protocol provides the answer to a command frame only with the next transmission triggered by the MCU; so, for example, the expected result of this STA_1 read, will be the SDO value of the next STA_0 read.
STA_0:0x4001 (read Status register 0, expected results OUT_ON_ERR = 0, OUT_OFF_ERR = 0, frame counter = 1)
OFF diagnosis:
Before sending the next SPI command, remove jumper J25, otherwise the OUTPUT LED is seen as a load for CH6, masking the open load diagnosis.
DIAG_OFF_EN: 0xB7FE (enable OFF diagnosis on all channels to detect open load or short circuit to GND, frame counter = 0)
STA_0: 0x4001 (read Status register 0: expected result DIS = 0, NRES = 1, IDLE = 1, IN1 = 0, IN0 = 0, OUT_ON_ERR = 0, OUT_OFF_ERR = 1, frame counter = 1)
DIAG_OPL_OFF: 0x4C00 (read open load in OFF diagnostic: expected results OUT6 = 1 because unconnected, frame counter = 0)
DIAG_SHG: 0x5401 (read short to GND diagnostic: expected results OUT7 = 1 because shorted to GND, frame counter = 0)
After OFF diagnosis completion, jumpers J25 can be closed, so there will be visual feedback at channels switched on.
Switch on the loads
IN0 =1, IN1 = 1 (switch on CH0 & CH5, through J22-J23)
PWM_SPI: 0x9B48 (all SPI driven channels are switched on, frame counter = 0) PWM_GEN_DC: 0xAFFF (configure PWM GEN duty cycle at 100 %, the expected effect is CH3
fully on, frame counter = 1)
PWM_LED_DC: 0XB3FD (configure PWM LED duty cycle at 100 %, the expected effect is CH2 fully on, frame counter = 0)
ON diagnosis
STA_0: 0x4001 (read Status register 0: expected result DIS = 0, NRES = 1, IDLE = 1, IN1 = 1, IN0 = 1, OUT_ON_ERR = 1, OUT_OFF_ERR = 0, frame counter = 1)
DIAG_OVC_OVT:0x4802 (read the overcurrent and overtemperature diagnosis, expected results OUT5 = 1 since a bulb lamp has been used; refer to the L9800 datasheet for further details. Frame counter = 0)
DIAG_OVC_OVT_RLW: 0XBFFD (clear all the overcurrent and overtemperature diagnosis, expected result reading DIAG_OVC_OVT again all the diagnosis has been cleared. Frame counter = 1)
