MITSUBISHI <CONTROL / DRIVER IC>
M54646AP
2-PHASE STEPPER MOTOR DRIVER
DESCRIPTION
The M54646AP is a semiconductor IC to drive bipolar stepper
motors by controlling winding current with reference to a
designated current level.
FEATURES
q Wide driver voltage range (10 – 40V)
q Wide output current control range (20 – 800mA)
q Bipolar and constant current control
q Built-in flywheel diode
q 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 VR (pins
2 and 27 ).
Provided with control circuits that output two phases, this IC is
sufficient to drive a two-phase bipolar stepper motor.
