AN379: Application Circuit Using L6204 for Bipolar Stepper DC Motor Applications

AN379 Using L6204 for Bipolar Stepper DC Motor Applications. The L6204 is a DMOS dual full bridge driver mainly designed to drive bipolar stepper motors. All the inputs are TTL/CMOS compatible and each bridge can be enabled by its own dedicated input. The windings current can be regulated by sensing the voltage drop across two low value resistors at the low end of both the bridge: this is the feedback for the current controller
