The reference design has the following
sub-blocks:
- Three-phase power stage including gate drivers and FETs
- Motor position sensor (three Hall latches) interface for sensored trapezoidal
control
- DC bus low-side current sensing
for torque control and software current limit provided by the MCU
- MOSFET temperature sensing using onboard temperature sensor
- Host controller to implement the necessary motor control algorithms, sensing,
and protections
