PT5139 普誠科技 雙H橋電機驅動器
DESCRIPTION
The PT5139 is a dual H-bridge motor driver which candrives two brushed DC motors or a single bipolarstepper motor, solenoids or other inductive loads. Eachbridge driver includes a PWM current regulationcircuitry to limit the winding current. The H-bridgedriver is consists by all of N-channel MOSFETs.The device have built-in protection features, includesunder-voltage lockout (UVLO), over current protection(OCP) and thermal shutdown (TSD). A fault flag outputis available to indicates the OCP or TSD conditions ishappens.
