Description

Functional Diagram

The US72 and US73 provide a monolithic

Out1

Out2

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.

Amp.

US73: The Rotation Detector (RD) / Alarm

Signal version has a low output in the normal

condition. When a locked rotor condition occurs

the RD changes to a high state.
