L6226 Datasheet PDF - STMicroelectronics

DESCRIPTION
The L6226 is a DMOS Dual Full Bridge designed for motor control applications, realized in MultiPower BCD technology, which combines isolated DMOS Power Transistors with CMOS and bipolar circuits on the same chip. Available in PowerDIP24 (20+2+2), PowerSO36 and SO24 (20+2+2) packages, the L6226 features thermal shutdown and a non-dissipative overcurrent detection on the high side Power MOSFETs plus a diagnostic output that can be easily used to implement the overcurrent protection.
