Stepping Motor Driver IC


PT5139

The PT5139 is a dual H-bridge motor driver which can drives two brushed DC motors or a single bipolar stepper motor, solenoids or other inductive loads. Each bridge driver includes a PWM current regulation circuitry to limit the winding current. The H-bridge driver is consists by all of N-channel MOSFETs.

The device have built-in protection features, includes under-voltage lockout (UVLO), over current protection (OCP) and thermal shutdown (TSD). A fault flag output is available to indicates the OCP or TSD conditions is happens.
