SDC281

Smart Two-Phase DC Fan Driver Datasheet SDC281 General Description The SDC281 is a two-phase brushless DC fan motor driver, which is built in Hall effect sensor. The driver includes lock detection and auto-restart functions. The built-in chopper amplifier can dynamically adjust the input offset voltage. It greatly improves the sensitivity of the magnetic. The output uses the soft-switch that greatly reduces the phase-switch noise. The power switch is application in advanced LDMOS technology to effectively reduce the on-resistance. The peak current is highly to 1200mA. Features  Widely operating voltage range: 2.5V~20V  High output peak current to 1200mA  Continuous output current to 600mA  High sensitivity Hall effect sensor IC: ±25GS  Soft-switch to reduce phase-switch noise  Built-in output protection clamping circuit  Built-in lock detection and auto-restart functions  Built-in thermal shutdown protection  Reverse voltage protection Applications  Br...
