GENERAL DESCRIPTION
FS211 2 PHASE DC MOTOR DRIVE IC 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 components, 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. FEATURES
