The MCF8316A provides a single-chip, code-free sensorless FOC solution for customers driving speed-controlled 12- to 24-V brushless-DC motors (BLDC) or Permanent Magnet Synchronous motor (PMSM) up to 8-A peak current. The MCF8316A integrates three 1/2-H bridges with 40-V absolute maximum capability and a very low RDS(ON) of 95 mΩ(high-side + low-side). Power management features of an adjustable buck regulator and LDO generate the 3.3-V or 5.0-V voltage rails for the device and can be used to power external circuits.

The algorithm configuration can be stored in non-volatile EEPROM, which allows the device to operate stand-alone once it has been configured. The device receives a speed command through a PWM input, analog voltage, variable frequency square wave or I2C command. There are a large number of protection features integrated into the MCF8316A, intended to protect the device, motor, and system against fault events.
