Smart Two-Phase DC Fan Driver

General Description

SDC281

Features

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.



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
