Description

The MCF8329HS-Q1 provides a single-chip, code-free sensorless FOC solution for driving 12V or 24V automotive brushless-DC motors (BLDC) or Permanent Magnet Synchronous motors (PMSM) up to 2.5kHz (electrical speed). The MCF8329HS-Q1 provide three half-bridge gate drivers, each capable of driving high-side and low-side N-channel power MOSFETs. A trickle charge pump is included to support 100% duty cycle. The MCF8329HS-Q1 can operate from a single power supply.

The algorithm configuration can be stored in non-volatile EEPROM, which allows the device to operate stand-alone once it has been configured. There are a large number of protection features integrated into the MCF8329HS-Q1, intended to protect the device, motor, and system against fault events.

MCF8329HS-Q1 is available in a 32-pin, 0.5mm pin pitch, 6x4mm, wettable flank WQFN package (RRY).
