The MCF8315C-Q1 provides a single-chip, code-free sensorless FOC design for customers driving speed-controlled 12 to 24V brushless-DC motors (BLDC) or Permanent Magnet Synchronous motor (PMSM) up to 4A peak current. The MCF8315C-Q1 integrates three ½-bridges with 40V absolute maximum capability and a low RDS(ON) of 240/250mΩ (high-side + low-side FETs). MCF8315C-Q1 integrates power management circuits including a voltage-adjustable 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 standalone after the device is 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 MCF8315C-Q1, intended to protect the device, motor, and system against fault events.

MCF8315C-Q1 is available in two packages: 40-pin 7mm × 5mm wettable-flank QFN (RGF) and 32-pin 6mm × 4mm wettable-flank QFN (RRY).
