SINGLE PHASE DC MOTOR DRIVE IC

GENERAL DESCRIPTION

The FS319, a 1-chip composed of hall sensor and output coil drivers, applied to a

single-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.

Using few external components, FS319, a high performance integrated IC, is designed for a

single-phase DC motor circuit.

The circuit diagram of the typical application example is as

below.
