PT5139

Dual H-Bridge Motor Driver

DESCRIPTION

FEATURES

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.



Wide Power Supply Voltage Range: 2.7V to 15V

Two Internal Full-Bridge Drivers

Internal Charge Pump for the High-Side Driver

Low Quiescent Current: 1.1mA

Low Sleep Current: 1μA

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.

Thermal Shutdown and Under-Voltage Lockout

Protection



Over Current Protection (OCP)

Thermally-Enhanced Surface-Mount Package

Low MOSFET On Resistance (HS: 600mΩ; LS:

570 mΩ)

APPLICATIONS



Digital Still Cameras

POS Printers

Video Security Camera

Robotics

Battery Powered Toys
