GENERAL DESCRIPTION
FS209
2-PHASE DC MOTOR DRIVE IC
The FS209, a 1-chip composed of hall sensor and output coil drivers, applied to a 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 up to 0.45A and operating voltage range is from 2.0V ~ 20V. Using few external components, FS209, 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.
