    ... DUAL FULL-BRIDGE PWM MOTOR DRIVER The UDN2917EB dual bridge is designed to drive both windings of a bipolar stepper motor. Output current is sensed and con- trolled independently in each bridge by an external sense resistor (R ), internal com- S parator, and monostable multivibrator. When the bridge is turned on, current ...
