1 Introduction

Some of the common challenges in tuning a Sensorless Trapezoidal Control-based Motor driver are minimizing motor startup time, acceleration and deceleration slew rate and improving system efficiency. Motor startup time is very critical in applications such as fuel pumps. With the MCT8316A, system designers can minimize the motor start-up time by configuring the motor start-up parameters. Acceleration and deceleration slew rate is critical in applications such as medical CPAP blowers. For integrated control motor drivers, temperature is often a critical design specification that cannot be violated. With the MCT8316A, system designers can minimize power losses by configuring PWM output frequency, PWM mode, ASR and AAR.
