DESCRIPTION

The L6223 is a programmable integrated system

for driving a unipolar stepper motor. It is realized

in Multipower BCD technology. The DMOS output

stage, realized by a single upper DMOS switch

and four lower DMOS, can deliver up to 1A/phase

with motor supply voltages up to 46V.

All inputs are CMOS and microprocessor compat-

ible. An internal 6-bit shift register allows the de-

vice to be programmed to select different duty cy-

cles in open loop mode and different chopping

frequencies in closed loop mode. When the cur-

rent control is in closed loop mode it is also possi-

ble to select a reduced current chopping level to

optimize system efficiency. The L6223 is de-

1/33
