US73 - (US72 / US73) Single Coil Fan Driver

This page provides the datasheet information for the US73, a member of the US72 (US72 / US73) Single Coil Fan Driver family.

Datasheet Summary

Description

The US72 and US73 provide a monolithic solution for driving single-coil fans.

The bridge drivers provide bi-directional current through the single phase motor winding.

US72: The tachometer/Frequency Generator (FG) version produces a logic signal, which is aligned with the Hall plate signal.

Features

Full Bridge Driver High Sensitivity Hall Sensor Locked Rotor Shutdown and Auto-Restart Power-Efficient CMOS and Power MOSFETs Integrated tachometer (US72) or alarm (US73) signal outputs.
