Description

The AH5792 is a single chip solution for driving single-coil brush-less DC fans and motors. The AH5792 employs a bidirectional full bridge driver output stage for single coil fan motor applications. The device includes features such as Rotor Lock Protection with rotor lock detection and automatic self-restart to avoid damage to the coil when the rotor is blocked.

Features

• Support single-phase full wave min fan driver

• Built-in Hall sensor input amplifier

• Low voltage startup ( Vdd=1.8V )

• Lock detection and automatic self-restart

• Without external timing capacitor, Reduces the numbers of external component required

• FG output

• Low profile package : SOT553 and SOT89-5L

• “Green” Molding Compound

Applications

• 3.3V / 5V Min. DC Fans (Eight Pole)
