DESCRIPTION

The MP6507 is a bipolar stepper-motor driver

with dual, built-in full-bridges consisting of N-

channel power MOSFETs.

It operates from a supply voltage range of 2.7V

to 15V, and can deliver motor current up to

700mA per channel. The internal safety

features include sinking and sourcing current

limits implemented with external sensors,

under-voltage lockout and thermal shutdown.

An over-temperature output flag is available to

indicate thermal shutdown.

The

MP6507

is

available

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.

FEATURES

 Wide 2.7V-to-15V Input Voltage Range

 Two Internal Full-Bridge Drivers

 Low MOSFET On Resistance (HS: 500mΩ;

LS: 500 mΩ)

 Internal Charge Pump for the High-Side

Driver

 Low Quiescent Current: 1.1mA

 Low Sleep Current: 1μA

 Thermal Shutdown and Under-Voltage

Lockout Protection

 Over-Temperature Output Flag

 Thermally-Enhanced Surface-Mount

Package

APPLICATIONS

 POS Printers

 Video Security Camera

 Digital Still Cameras

 Battery Powered Toys
