0.7 A 6.8 V Dual H-Bridge Motor

Driver

The 17533 is a monolithic dual H-Bridge power IC ideal for portable

electronic applications containing bipolar stepper motors and/or brush

DC-motors (e.g., cameras and disk drive head positioners).

The 17533 operates from 2.0 V to 6.8 V, with independent control of

each H-Bridge via parallel MCU interface (3.0 V- and 5.0 V-compatible

logic). The device features built-in shoot-through current protection

and an undervoltage shutdown function.

The 17533 has four operating modes: Forward, Reverse, Brake,

of 1.2

Ω (max @ 25°C).

The 17533’s low output resistance and high slew rates provide

efficient drive for many types of micromotors.

Features

• Output Current 0.7 A (DC), 1.4 A (Peak)

• Shoot-Through Current Protection Circuit

•3.0 V/5.0 V CMOS-Compatible Inputs

• PWM Control Input Frequency up to 200 kHz

• Built-In 2-Channel H-Bridge Driver

• Low Power Consumption

• Undervoltage Detection and Shutdown Circuit

• Pb-Free Packaging Designated by Suffix Code EV
