UC3717A Stepper Motor Drive Circuit

The UC3717A is an improved version of the UC3717, used to switch drive the current in one winding of a bipolar stepper motor. The UC3717A has been modified to supply higher winding current, more reliable thermal protection, and improved efficiency by providing integrated bootstrap circuitry to lower.

UC3717A Features

* Full-Step, Half-Step and Micro-Step Capability

* Bipolar Output Current up to 1A

* Wide Range of Motor Supply Voltage 10-46V

* Low Saturation Voltage with Integrated Bootstrap

* Built-In Fast Recovery Commutating Diodes

* Current Levels Selected in S
