The MCF8315A 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 4-A peak current. The MCF8315A integrates three ½-bridges with 40-V absolute maximum capability and a low R DS(ON) of 240 mΩ (high-side + low-side FETs). MCF8315A integrates power management circuits including an voltage-adjustable buck regulator (3.3 V / 5 V, 170-mA) and LDO (3.3 V / 20 mA) 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 it has been configured. The device receives a speed command through a PWM input, analog voltage, variable frequency square wave or I 2C command. There are a large number of protection features integrated into the MCF8315A, intended to protect the device, motor, and system against fault events.
