AH5798 - SINGLE PHASE HALL EFFECT LATCH SMART FAN MOTOR CONTROLLER

Description

The AH5798 is a single chip solution for driving single-coil brush-less DC fans and motors.

The AH5798 employs a bidirectional full bridge driver output stage for single coil fan motor applications.

The soft switching driver generates the low noise operating for DC fans.

Features

  • Support single-phase full wave DC fan driver Built-in Hall sensor input amplifier Low voltage startup ( Vdd=1.8V ) Lock detection and automatic self-restart Soft switching for low noise DC fans Without external timing capacitor, Reduces the numbers of external component required Thermal protection FG output Low profile package: SOT89-5L SOT89-5L: Available in “Green” Molding Compound (No.
