formance, low noise, single-phase, Direct Current Brushless (BLDC) motor pre-driver with variable PWM speed control and current control suitable for fan and blower motors. For system flexibility the motor speed can be controlled by either an external PWM control signal or by a DC voltage signal from an external control voltage or from a Thermistor network. To prevent motor inrush current the device has a soft start feature. To help protect the motor coil, the ZXBM1021 provides rotor lock protection which shuts down the output drive if rotor lock is detected. The device automatically re-starts with soft-start when the rotor
