A4941 driver equivalent, three-phase sensorless fan driver.
* Sensorless (no Hall sensors required)
* Soft switching for reduced audible noise
* Minimal external components
* PWM speed input
* FG speed output <.
A pulse wave modulated (PWM) input is provided to control motor speed, allowing system cost savings by eliminating exte.
The A4941 three-phase motor driver incorporates BEMF sensing to eliminate the requirement for Hall sensors in fan applications. A pulse wave modulated (PWM) input is provided to control motor speed, allowing system cost savings by eliminating externa.
