SDC477
General Description
Features
The SDC477, is an integrated Hall sensor with H-bridged
Toutput driver designed for brushless DC motor
applications. The high sensitivity of Hall-effect sensor is
Nsuitable for motors from mini-type CPU coolers to
Eblowers and DC fans. Typical operation current is 250mA
OCUMand operating voltage range is wide.
One-chip hall sensor
Wide operating voltage range: 3.8V~20V
Output sink current up to 250mA
Output thermal shutdown protection
Package : TO-94
Applications
Brushless DC motor
Brushless DC fan
Revolution counting
Speed measurement
