AM4961A
SINGLE PHASE FULL WAVE PWM MOTOR DRIVER
Description
The AM4961A is highly integrated feature rich single phase Brushless Direct Current (BLDC) full wave motor driver with PWM control function for fans, blowers and extractors.
For system flexibility the motor speed can be controlled by either an external PWM signal or by a DC voltage or from a Thermistor network. Based on the input signal, the AM4961A adjust the output duty cycle.
To help protect the motor coil, the AM4961A provides a rotor lock protection which shuts down the output if rotor lock is detected. The device automatically re-starts when the rotor lock is removed.
