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. BLOCK DIAGRAM

ORDERING NUMBERS: L6204 L6204D

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 operating temperatures no external heatsink is required.
