SDC281

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.
