DESCRIPTION

The L6205 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 PowerDIP20 (16+2+2),

PowerSO20 and SO20(16+2+2) packages, the

L6205 features a non-dissipative protection of the

high side PowerMOSFETs and thermal shutdown.
