Introduction

AI Translation

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. To help interface to external system for monitoring the motor status and speed, AM4961A provides open drain Rotor lock detect alarm output (RD) pin and a tachometer output Frequency Generator (FG). The FG output is the magnetic change frequency. The AM4961A is available in SSOP-16 and HTSSOP-14 packages.
