A4941 A4941GLPTR-T A4941GLP-t Three-Phase Sensorless Fan Drive
Features and Benefits
Sensorless (no Hall sensors required)
Soft switching for reduced audible noise
Minimal external components
PWM speed input
FG speed output
Low power standby mode
Lock detection
Optional overcurrent protection
Description
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 external variable power supply. PWM input can also be used as an on/off switch to disable motor operation and place the IC into a low power standby mode.
The A4941 is provided in a 16-pin TSSOP package (suffix LP) with an exposed thermal pad. It is lead (Pb) free, with 100% matte tin leadframe plating.
