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-dissipa-

tive overcurrent detection on the high side Power

MOSFETs plus a diagnostic output that can be easily

used to implement the overcurrent protection.
