FS211F PDF File ( Datasheet )

Technology GENERAL DESCRIPTION FS211F 2 PHASE DC MOTOR DRIVE IC 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
