AM8935

AM8935 Motor Driver ICs 3-Phase Sensor-less Fan Motor Driver AM8935 The AM8935 is a 3-Phase sensor-less DC fan motor driver IC. It senses the BEMF (Back Electro-Motive Force) of the motor in rotation and provides corresponding commutation current to the motor. Rotation speed can be controlled by PWM input signal. The drivers include Lock Detection, Thermal Shutdown, and Over-current limiter. Maximum output current is 1000mA.  Features Confidential 1) Operation voltage 3 to 16V 2) Direct PWM speed control 3) Built-in FG & RD 4) Soft start function 5) Forward and Reverse control 6) Lock detection/Automatic restart function  Absolute Maximum Ratings (Ta = 25℃) 7) Over current limiter 8) Over-voltage protection 9) Thermal shutdown protection 10) Soft switching technique to reduce acoustic noise Parameter Symbol Limits Unit Supply voltage VREG strength voltage Output Peak current VCC VREG Iomax 18 6 1200 V V mA Output Continuous current Io 550 mA FG & RD output vol...
