STMicroelectronics L6223
The L6223 is a programmable integrated system for driving a unipolar stepper motor. It is realized in Multipower BCD technology. The DMOS output BLOCK DIAGRAM MULTIPOWER BCD TECHNOLOGY POWERDIP 16+2+2 ORDERING NUMBER : L6223 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.DESCRIPTION
It is realized in Multipower BCD technology. All inputs are CMOS and microprocessor compatible. An internal 6-bit shift register allows the device to be programmed to select different duty cycles in open loop mode and di
