2.4 SCHEMATIC DESCRIPTION
2.4.1 Current Sense Amplifier (CSA)
The CSAs 1 and 2 are amplifying the string current of phase C and phase B while the CSA 3 amplifies the sum current of all three strings. All the 3-Current Shunt Amplifiers CSA are set to an offset of 1.637V. The reference supply of half of the microcontroller supply voltage level allows measuring positive as well as negative voltages in the same range.
DS50003171A-page 14
2022 Microchip Technology Inc. and its subsidiaries
Installation and Operation
The third CSA's offset can alternatively be switched down to 0V, for only positive current measurement.
The amplification gain of all the three CSA's is adjusted to 15.
The op amps are switched as inverters. The positive clamps of the shunts are connected to the inverted inputs and the shunt's negative clamps are connected each to the noninverted inputs.
In combination with the 10mOhm shunt, a current of 10A should be possible to measure per string. For higher current, lower shunt resistors RSh1, RSh2, RSh3 need to be installed.
2.4.2 HALL Sensor or QEI interface
The purpose of the connector J8 is to connect rotor position feedback sensors. The microcontroller input signals are suitable to take position signals back from either three HALL sensors or a Quadrature Encoder Interface QEI. The pinning is shown in Table 2-6.

VBOOT and Bootstrap Circuitry.
3.1 VBOOT CAPACITOR PRECHARGE
VBOOT is supplied as soon as the output enable pin OE is set to active.
For VDD supply voltages below the Charge Pump operation threshold voltage level of 13V, VBOOT is supplied from the charge pump. For VDD supply voltages higher than Charge Pump operation threshold voltage level, the VBOOT is directly supplied out of the VDD via an LDO.
Before usage of the VBOOT function, the user must ensure VBOOT is fully charged.
VBOOT is enabled after Power On Reset, with the rising edge of Output Enable pin OE. The charging time depends on the size of VBOOT. This is typically 1ms for a VBOOT capacitor size of 10µF. This time is valid for both charge pump and 12-V-LDO charging.

MCP8022 BLDC Motor Driver Development Board User Guide
3.2 BOOTSTRAP CAPACITOR PRECHARGE
The low-side gate drivers are getting directly supplied out of the VBOOT capacitor while the high-side gate drivers need a bootstrap capacitor for high-voltage gate supply.
Before high-side gate driver activation, be certain the bootstrap capacitors are fully charged.
The bootstrap capacitors are charged by activation of the corresponding low-side gate drivers. The low-side drivers switch the anode of the low capacitors across the corresponding motor clamp to power ground. This allows the bootstrap capacitors to charge out of the VBOOT capacitors across the bootstrap diode.
The VBOOT capacitor should be fully loaded for charging the bootstrap capacitors. The VBOOT capacitor powers the low-side gate driver as well as directly powering the bootstrap capacitor's charging process.
The charge inrush current of the bootstrap capacitors may trigger the overcurrent protection of the MCP8022. The low ohmic capacitors act almost like a short circuit and will draw a high peak current. Depending on the capacitor size, the peak can last a few hundred microseconds. Bootstrap charge precautions need to be taken, which can be sequential charging of the three bootstrap capacitors. This is not as efficient as if the three clamps are connected to each other across the motor coils. A more practical solution may be a PWM-controlled bootstrap capacitor precharge.
It must be considered that overcurrent protection is triggered and will lock further operation of the MCP8022 by a FAULT signal.

USER GUIDE
Chapter 4. Software
4.1 SOFTWARE ARCHITECTURE
The open-source demonstration software package is created using multiple software tools and techniques. The demo is available as the MPLAB X IDE project. The software architecture builds-up from some layers. The low-level peripherals are configured by the MPLAB Code configurator. Also, some higher-level MCC libraries are used like X2C® and MCP8022 controller libs. The motor control algorithm is implemented by a model-based approach with Scilab and X2C tools. The X2C ecosystem also enables the user to do run-time monitoring, control algorithm parameter tuning and debugging via the UART port.
FIGURE 4-1:
SW Architecture.
The demo code implements a sensorless, field-oriented motor control to demonstrate the MCP802x family capabilities. Therefore, this documentation focuses on the development board, not on the motor control algorithm. For further details about the motor control technique used, please refer to the application note AN1292 (see https://ww1.microchip.com/downloads/en/AppNotes/01292A.pdf).
4.2 MICROCHIP MPLAB CODE CONFIGURATOR MCC
The software package was generated by using Microchip's MPLAB Code Configurator (MCC). All the relevant configurations and middleware, including the ones for MCP8022, are part of MCC. For the MCP8022 DE2 register setup and all the UART communication created with the MCC, see Figure 4-1 for the used peripherals and MCP802x MCC Easy Setup Window.

DS50003171A-page 19
MCP8022 BLDC Motor Driver Development Board User Guide
FIGURE 4-2:
MCP802x MCC Easy Setup Window.
The I/O configuration is also done by MCC. Figure 4-2 shows a part of the configuration. Hint: The MCP8022_OE is important to set, otherwise the MCP802X library cannot work properly.
FIGURE 4-3:
Pin Module Settings.
MCC generates a framework project with peripheral initialization functions. The following flowcharts show the peripherals are initialized and configured by the generated MCC functions at the beginning of the main routine. Then the MCP8022 is also initialized manually. Finally, the idle loop handles the diagnostics. The MCP802X high-level management functions are implemented using the middleware MCC library. These functions are organized in the MCP802X task function and executed in the Timer 1 interrupt. MCP802X can send unsolicited error messages in case of HW fault. These are handled at the UART RX (DE2) interrupt. To check the errors with the polling method, use the getStatus functions. It is also possible to use callback (push) method to increase response time. To do so, override the weak "Status_Notification" callback function to get notification at the application layer immediately after the error message arrives. Limit the callback function execution time, as it is running in the UART interrupt.

The details of the MCC configuration are not part of the documentation as it can be opened in MPLAB X. The graphical peripheral configuration in MCC is self-explanatory, when added together with the schematics portion of this document. For further details on how to use the MCC, follow this link.
4.3 X2C - RAPID PROTOTYPING (MODEL-BASED SOFTWARE DESIGN)
The field-oriented motor control algorithm is implemented in a Scilab model. The compilable C code is generated from this model by the X2C® toolbox. This motor control model is part of the source code that can be opened with the free Scilab software. The model itself also contains a motor sub-block that is not part of code generation, however, enables PC simulation is enabled. (shown in the green box in Figure 4-5).

MCP8022 BLDC Motor Driver Development Board User Guide
The high-level workflow with Scilab and X2C is demonstrated in Figure 4-6 and Figure 4-7. As described above, the MCC creates the peripheral configuration, the drivers and framework project that will execute the model code generated from Scilab.
FIGURE 4-6:
MPLAB X, MCC and Scilab, X2C Integrating Together.
The workflow looks like the following [Figure 4-7]:
1. Use Scilab to work on the model and simulate on PC 2. Use X2C Communicator to generate code from the model 3. Use MPLAB X to program the device and debug, if necessary 4. Use X2C communicator's scope window to monitor real time analog signals
FIGURE 4-7:
Working with Scilab and MPLAB X.
The FOC model calculation is executed in the ADC interrupt when the phase current measurements are ready. The ADC sampling is synchronized with the PWM frequency, which is 10kHZ. Therefore, the model execution period is 100 us. At the beginning of the interrupt, the model "inport" variables are updated according to the phase currents measured by ADCs. Then the motor control model calculation function is executed. Finally, the results of the calculation, the outport variables of the model, are scaled and passed to the peripherals like PWM duty cycle.
Diagnostics:
The X2C framework provides additional features like run-time parameter change in control algorithm and virtual oscilloscope to monitor analog signal chains in the model. The main idle loop contains the necessary diagnostics functions to provide the communication interface via the J1 VCP Virtual COM Port.
