GENERAL DESCRIPTION
2 PHASE DC MOTOR DRIVE IC
The FS211, a 1-chip posed 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 0.3A 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 ponents, FS211,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.
