GENERAL DESCRIPTION
FS210
2-PHASE DC MOTOR DRIVE IC
The FS210, 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 2.8V ~ 20V.
Using few external components, FS210, a high performance integrated IC, is designed for a
single-phase DC motor circuit.
