The S3, S4 control the Motor2, respectively _ Contact info įull-featured Dual Hbridge - Dueal non-shortin H-bridge with brake_įull-featured Dual H-bridge - I had always assumed that dynamic braking would be most effective at higher speeds. The S1, S2 switches control the ON/OFF and the moving direction of Motor1. Each motor can be independently controlled. in this Dual stepper motor drivers design we use two UDN2540B to drive two stepping motors at the same speed. The typical applications include print heads, relays, solenoids, and stepper motor control. Each output can sink up to 1.8A continuous. John Girardĭual Stepper Motor drivers using UDN2542 - The UDN2540B is a quad darlington power driver, manufactured by Allegro. it is a flexible design allowing for unipolar and bipolar motors _ Designed by J. it also provides an output signal when a step is being taken. The circuit accepts two 2-bit words that command each of the motors to go forward, backward, hold a position, or to idle. Dual Stepper Motor Driver for a Robot Differential Drive - This article describes the hardware and the software used to control two stepper motors suitable for a robot differential drive.
