The MCT8316A provides a single-chip, code-free sensorless trapezoidal solution for customers requiring high speed operation (up to 3kHz electrical) or very fast startup time (<50ms) for 12- to 24-V brushless-DC motors up to 8-A peak current. The MCT8316A integrates three 1/2-H bridges with 40-V absolute maximum capability and a very low RDS(ON) of 95 mΩ (high-side + low-side). 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.

Sensorless trapezoidal control is highly configurable through register settings (MCT8316AV) or hardware pins (MCT8316AT) ranging from motor start-up behavior to closed loop operation. Register settings for MCT8316AV 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, variable frequency square wave or I2C command. There are a large number of protection features integrated into the MCT8316A, intended to protect the device, motor, and system against fault events.
