A4941 Thông tin chi tiết sản phẩm

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.

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

• Variant A automotive qualified to AEC-Q100 Grade 2
