FS211F

2 PHASE DC MOTOR DRIVE IC

Technology

GENERAL DESCRIPTION

The FS211F, a 1-chip composed of hall sensor and output coil drivers, applied to 2-phase DC

motor. The high sensitivity of Hall effect sensor is suitable for motors from mini-type CPU

coolers to blowers and DC fans. Typical operation current is 0.4A and operating voltage range is

wide. FG signal, an open collector, provides a square waveform output for the detection of the

motor speed.

Using few external components, FS211F, a high performance integrated IC, is designed for a

2-phase DC motor circuit. The circuit diagram of the typical application example is as below.
