MCF8329A/MCF8329A-Q1 Three-Phase BLDC Gate Drivers

Texas Instruments MCF8329A/MCF8329A-Q1 FOC Three-Phase BLDC Gate Drivers provide a single-chip, code-free sensorless FOC solution for applications driving brushless-DC motors (BLDC) or Permanent Magnet Synchronous motors (PMSM). The MCF8329A/MCF8329A-Q1 provides three half-bridge gate drivers. Each is capable of driving high-side and low-side N-channel power MOSFETs. The device uses a bootstrap circuit that generates the correct gate drive voltages using an internal charge pump. This feature enhances the high-side MOSFETs. A trickle charge pump is included to support a 100% duty cycle. The MCF8329A/MCF8329A-Q1 supports a wide input supply range of 4.5V to 60V and can operate from a single power supply.
