MCF8316A Sensorless FOC Integrated FET BLDC Driver | Datasheet Preview

The Texas Instruments MCF8316 A is a single-chip, code-free, sensorless, Field Oriented Control solution for customers driving speed-controlled 12 to 24 volt brushless DC motors or Permanent Magnet Synchronous motors with up to 8 amps peak current. The MCF8316 A integrates three half H bridges with 40 volt absolute maximum capability and a very low RDS(ON) of 95 milliohms. An adjustable buck regulator and LDO generate the 3.3 or 5 volt voltage rails for the device and can be used to power external circuits. The algorithm configuration can be stored in nonvolatile EEPROM, which allows the device to operate stand-alone once it has been configured. The device receives speed commands through a PWM input, an analog voltage, a variable frequency square wave, or I squared C commands. The MCF8316A includes multiple protection features to protect the device, motor, and system against fault events.
