It is equipped with three high-side pre-FET drivers and three low-side drivers which are controlled by an external microcontroller (MCU). The power for the high side is supplied by a charge pump and no bootstrap cap is needed. For commutation, this integrated circuit (IC) sends a conditional motor drive signal and output to the MCU. Diagnostics provide undervoltage, overvoltage, overcurrent, overtemperature and power bridge faults. The motor current can be measured using an integrated current sense amplifier and comparator in a battery commonmode range, which allows the motor current to be used in a high-side current sense application. Gain is attained by external resistors. ...
