The MCT8316A-Q1 provides a single-chip, code-free sensorless trapezoidal device for customers requiring high speed operation (up to 3kHz electrical) or very fast startup time (<50ms) for 12 to 24V brushless-DC motors up to 8A peak current. The MCT8316A-Q1 integrates three 1/2-H bridges with 40V absolute maximum capability and a very low RDS(ON) of 95mΩ (high-side + low-side). Power management features of an adjustable buck regulator and LDO generate the 3.3V or 5.0V voltage rails for the device and can be used to power external circuits.

Sensorless trapezoidal control is highly configurable ranging from motor start-up behavior to closed loop operation through register settings. These settings can be saved in non-volatile EEPROM, which allows the device to operate stand-alone once the device 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-Q1, intended to protect the device, motor, and system against fault events.
