PTC PT5139-HT-TP

The PT5139 is a dual bridge motor driver which has two H-bridge drivers, and can drive two DC brush motors, a bipolar stepper motor, solenoids, or other inductive loads. It operates from 2.7V to 15V, and can deliver load current up to 700mA per channel. The output driver block of each H-bridge consists of N-channel power MOSFETS configured as an H-bridge to drive the motor windings. Each H-bridge includes circuitry to regulate or limit the winding current. The internal safety features include sinking and sourcing current limits implemented with external sensors, under-voltage lockout, over current protection (OCP) and thermal shutdown. An over-temperature output flag is available to indicate thermal shutdown. The PT5139 is packaged in 16-pin, 5.0mm×6.4mm TSSOP-EP and TSSOP, 3mm×3mm and 4mmx4mm QFN package with an exposed thermal pad on the back.
