DESCRIPTION
The L6223A is a programmable integrated sys-
tem for driving a unipolar stepper motor. It is real-
ized in Multipower BCD technology. The DMOS
output stage, realized by a single upper DMOS
switch and four lower DMOS, can deliver up to
1A/phasewith 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 closedloop mode it is also possi-
ble to select a reduced current chopping level to
optimize system efficiency. The L6223A is de-
