1.4 Device Information

The MCF8315 is a 4.5V to 35V, 4A peak three-phase gate driver IC with integrated code-free sensorless field-oriented control (FOC) for motor drive applications. The internal sensorless FOC algorithm is highly configurable through register settings in a non-volatile EEPROM ranging from motor start-up behavior to closed loop operation, which allows for the device to operate stand-alone once the device has been configured.

The device provides three accurately trimmed and temperature-compensated half-bridge MOSFETS, gate drivers, a charge pump, a current sense amplifier, a linear regulator for the external load, and an adjustable buck regulator. The device can receive a speed command through a PWM input, analog voltage, variable frequency square wave, or I2C command. Internal protection functions are provided for undervoltage lockout, FET overcurrent, and overtemperature. The nFAULT pin indicates fault events detected by the protection features.
