The MCT8315A provides a single-chip, code-free sensorless trapezoidal solution for customers requiring high speed operation (up to 3 kHz electrical) or very fast start-up time (< 50 ms) for 12- to 24-V brushless-DC motors requiring up to 4-A peak current. The MCT8315A integrates three ½-bridges with 40-V absolute maximum capability and a low R DS(ON) of 240 mΩ (high-side + low-side FETs). MCT8315A integrates power management circuits including an voltage-adjustable buck regulator (3.3 V / 5 V, 170-mA) and LDO (3.3 V, 20 mA) that can be used to power external circuits.

Sensorless trapezoidal control is highly configurable (motor start-up/stop behavior, fault handling, closed loop operation) through register settings in a non-volatile EEPROM, which allows the device to operate stand-alone once it has been configured. The MCT8315A receives a speed command through a PWM signal, analog voltage, variable frequency square wave or I 2C instruction. There are a large number of protection features integrated into the MCT8315A to protect the device, motor, and system against fault events.
