The MCF8329A provides a single-chip, code-free sensorless FOC solution for applications driving brushless-DC motors (BLDC) or Permanent Magnet Synchronous motor (PMSM). The MCF8329A provides three half-bridge gate drivers, each capable of driving high-side and low-side N-channel power MOSFETs. The device generates the correct gate drive voltages using an internal charge pump and enhances the high-side MOSFETs using a bootstrap circuit. A trickle charge pump is included to support a 100% duty cycle. The MCF8329A can operate from a single power supply and supports a wide input supply range of 4.5 to 60 V.

The algorithm configuration can be stored in non-volatile EEPROM, which allows the device to operate stand-alone once it has been configured. Motor current is sensed using an integrated current-sensing amplifier supporting a single external shunt resistor. MCF8329A integrates a large number of protection features, intended to protect the device, motor, and system against fault events.
