40V (max) 8A (peak), sensorless FOC three-phase BLDC motor driver with UL-recognized variant

The MCF8316D provides a single-chip, code-free sensorless FOC device for driving 12 to 24V brushless-DC motors (BLDC) or Permanent Magnet Synchronous motor (PMSM) up to 8A peak current. The MCF8316D integrates three ½-bridges with 40V absolute maximum capability and a very low RDS(ON) of 95mΩ (HS+LS FETs). MCF8316D integrates a buck regulator (3.3V/5V, 170mA) and LDO (3.3V, 20mA) that can be used to power external circuits.

The FOC algorithm configuration can be stored in non-volatile EEPROM, which allows the device to operate stand-alone once the device 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 MCF8316D, intended to protect the device, motor, and system against fault events.
