The ZXBM1016 is a high efficiency, low noise, single-phase, DC brushless motor pre-driver with PWM variable speed control and current control suitable for fan and blower motors. High efficiency and low noise are achieved using a novel technique (patent pending) for commutation current control. The controllers are primarily intended to meet industry standard OEM fan specifications where external PWM control are applied, however, they can also be used with other thermal control techniques using an external voltage, PWM signal or thermistor.
