The MCF8316A provides a single-chip code-free sensorless FOC solution for customers driving speed-controlled 12- to 24-V brushless-DC motors with 8-A peak current capability. The MCF8316A integrates three 1/2-H bridges with 40-V absolute maximum capability and a very low RDS(ON) of 95mOhms (high-side plus low-side) to enable high power drive capability. Current is sensed using an integrated current sensing feature which eliminates the need for external sense resistors. Power management features of an adjustable buck regulator and LDO generate the 3.3-V or 5.0-V voltage rails for the device and can be used to power external circuits.

MCF8316A implements code-free Sensorless FOC, and so an external microcontroller is not required to spin the brushless-DC (BLDC) motor or Permanent Magnet Synchronous motor (PMSM). The algorithm configuration can be set 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, or I2C command.

There are a large number of protection features integrated into the MCF8316A, intended to protect the device, motor, and system against fault events.
