PRODMIX
The MCF8315C provides a single-chip, code-free sensorless FOC solution 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 integrates three ½-bridges with 40V absolute maximum capability and a low RDS(ON) of 250/265mΩ (high-side + low-side FETs). MCF8315C 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 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 wettable-flank QFN (RRY) and 24-pin 7.8x6.4mm HTSSOP (PWP).
