FD036KT-Sensorless brushless DC motor driver IC


FD036KT  Sensorless 3-phase brushless DC motor driver IC
General Description
Download
FD036 is a sensorless 3-phase brushless DC motor driver IC. It senses the BEMF (Back electromotive force) of the motor in rotation and provides corresponding commutation current to the motor. The use of sensorless technology means no hall sensors are needed and makes the motor fabrication easy and especially for the small and thin DC motors since the IC is placed outside of the motor assembly.
FD036 series ICs have the functions of variable speed control, tachometer signal output, rotation direction control and shutdown mode, the motor including FD036 IC can be controlled and detected by these features very easy from your system

Features
PWM (pulse width modulation) motor variable speed control
Built-in tachometer signal output (FG) for detection of motor speed
〃Soft-switching〃 technique to reduce vibration and acoustic noise
Thermal shutdown protection
Rotor lock shutdown drivers protection and auto-restart function
Direction of rotation control (FD036Ug only)
Shutdown mode with low standby current (FD036Ug only)
Package: MSOP8 (FD036KT) / MSOP10 (EP) (FD036Ug)
