M54646AP

2-Phase Stepper Motor Driver

REJ03F0044-0100Z

Rev.1.0

Sep.19.2003

Description

The M54646AP is a semiconductor IC to drive bipolar stepper motors by controlling winding current with reference to

a designated current level.

Features

•

Wide driver voltage range (10 – 40V)

Wide output current control range (20 – 800mA)

Bipolar and constant current control

Built-in flywheel diode

Built-in thermal protection circuit

Application

Office automation equipment such as printers, FDDs, HDDs and facsimiles

Function

M54646AP Integrated Circuit drives two-phase bipolar stepper motors while controlling winding current: It controls

winding current direction by inputting phases (pins 14 and 15) and, at the same time, controls winding current

amperage with terminals V_R(pins (2) and (27)).

Provided with control circuits that output two phases, this IC is sufficient to drive a two-phase bipolar stepper motor.
