Description

The L6226Q is a DMOS dual full bridge designed

for motor control applications, realized in

BCDmultipower technology, which combines

isolated DMOS power transistors with CMOS and

bipolar circuits on the same chip. Available in

QFN32 5x5 package, the L6226Q 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.
