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
Brushless DC fan motors
