The MCF8315C 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 MCF8315C integrates three ½-bridges with 40-V absolute maximum capability and a low RDS(ON) of 250/265 mΩ (high-side + low-side FETs). MCF8315C 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 I2C command. There are a large number of protection features integrated into the MCF8315C, intended to protect the device, motor, and system against fault events.
MCF8315C is available in two packages - 32-pin 6x4mm QFN (RRY) and 24-pin 7.x8x6.4mm HTSSOP (PWP)
