General Description

PBL 3717/2 is a bipolar monolithic circuit intended to control and drive the current in one winding of a stepper motor.

The circuit consists of a LS-TTL patible logic input stage, a current sensor, a monostable multivibrator and a high power H-bridge output stage with built-in protection diodes.

Two PBL 3717/2 and a small number of external ponents form a plete control and drive unit for LS-TTL or microprocessor-controlled stepper motor systems.
