L6204
APPLICATION DIAGRAM
CIRCUIT DESCRIPTION
L6204 is a dual full bridge IC designed to drive DC motors, stepper motors and other inductive loads. Each
bridge has 4 power DMOS transistor with R
(see fig. 3)
The 4 half bridges can be controlled independently by means of the 4 inputs IN!, IN2, IN3, IN4 and 2 en-
able inputs ENABLE1 and ENABLE2.
External connections are provided so that sensing resistors can be added for constant current chopper
applications.
