PBL3717-2 - Stepper Motor Drive Circuit

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 compatible logic input stage, a current sensor, a monostable multivibrator and a high power H-bridge output stage with built-in protection diodes.

Features

Half-step and full-step modes.
Switched mode bipolar constant current drive.
Wide range of current control 5 - 1200 mA.
Wide voltage range 10 - 50 V.
Designed for unstabilized motor supply voltage.
Current levels can be selected in steps or varied continuously.
