The LMD18245 is a fullbridge
power amplifier
which incorporates all the
circuit blocks required to
drive and control current in
a brushed type d.c. motor,
or one phase of abipolar
stepper motor. The multitechnology
process used to
build the device cambines
CMOS control and proteetion
ctrcuttry with DMOS
power switches on the same
monolithic structure. The
LMD18245 controls the
motor current via a flxed offtime
chopper technique.
