SDC281 - Smart Two-Phase DC Fan

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.

Key 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.

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.
