DESCRIPTION

The L6204 is a dual full bridge driver for motor
control applications realized in BCD technology
which combines isolated DMOS power transistors
with CMOS and Bipolar circuitson the same chip.
By using mixed technologyit has been possible to
optimizethe logic circuitry and the power stage to
achievethe best possibleperformance.
The logic inputs are TTL/CMOS compatible. Both
channelsare controlled by a separate Enable.
Each bridge has a sense resistor to control the
currenrt level.

ORDERING NUMBERS:

L6204 L6204D

The L6204 is mounted in an 20-lead Powerdip
and SO 24+2+2 packages and the four center
pins are used to conduct heat to the PCB. At nor­mal operating temperatures no external heatsink
isrequired.
