Two-Phase DC Fan Driver
Datasheet
SDC283
General Description
Features
The SDC283 is a one-chip solution for driving two-coil
Tbrushless DC cooling fans. Based on the advanced CMOS
process, the IC contains a Hall-effect sensor, dynamic
Noffset correction and low side output drivers.
EIn the case of power supply reverse connecting, the
internal protection diode can protect IC but not protect
OCUMcoil, a protection diode can be added if necessary
Wide operating voltage range: 3.5V~16V
150mA(AVG) output sink current
Building-in protection diode
Output thermal shutdown protection
Package: TO-94
Applications
Brushless DC motor
Brushless DC fan
Revolution counting
Speed measurement
IDENTIAL DTO-94
