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
