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 circuits on the same chip.

By using mixed technology it has been possible to

optimize the logic circuitry and the power stage to

achieve the best possible performance.

The logic inputs are TTL/CMOS compatible. Both

channels are controlled by a separate Enable.

Each bridge has a sense resistor to control the

currenrt level.

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 oper-

ating temperatures no external heatsink is re-

quired.
