Advance Information

0.7 A Dual H-Bridge Motor Driver

with 3.0V/5.0V Compatible Logic I/O

The 17529 is a monolithic dual H-Bridge power IC ideal for portable

electronic applications containing bipolar step motors and/or brush DC-motors

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

The 17529 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 on-board charge pump, as well as built-in shoot-through

current protection and an undervoltage shutdown function.

The 17529 has four operating modes: Forward, Reverse, Brake, and

Tri-Stated (High Impedance). The 17529 has a low total RDS(ON) of 1.2 Ω (max

@ 25°C).

The 17529’s low output resistance and high slew rates provide efficient

drive for many types of micromotors.

Features

• Low Total RDS(ON) 0.7 Ω (Typ), 1.2 Ω (Max) @ 25°C

• 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 Charge Pump Circuit

• Low Power Consumption

• Undervoltage Detection and Shutdown Circuit

• Pb-Free Packaging Designated by Suffix Code EV
