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.
