DESCRIPTION

The L6225 is a dual full bridge driver for motor control

applications manufactured with Multipower BCD

technology which combines isolated DMOS power

transistors with CMOS and bipolar circuits on the

same chip.

The Logic Inputs are CMOS/TTL and

The High Side switches are protected against unsafe

over current conditions.

Each full bridge is controlled by a separate Enable

and has a sense pin for the current sense resistor in-

sertion. Another feature is the thermal shutdown.

The L6225 is assembled in PowerDIP20(16+2+2),

PowerSO20 and SO20(16+2+2) packages.
