Micromotor Driver with Dual

3-Phase and Dual H-Bridge

Outputs

The 17559 is a monolithic quad H-Bridge power IC ideal for

portable electronic applications containing multiple brushless and

brush DC-motors.

The 17559 is designed to drive motors with supplies operating

from 0.9 V to 3.5 V, with independent control of each output bridge

via parallel 1.8 V to 3.6 V logic-compatible I/O. Each output bridge

has its own gate-drive and logic circuitry with built-in shoot-through

current protection.

max @ 25°C for each of the two H-Bridge outputs.

The 17559 can efficiently drive many types of micromotors owing

to its low output resistance and high output slew rates.

Features

• Two Separate Three-Phase Motor Drivers

• Two Separate H-Bridge Motor Drivers

• Low-Voltage Detection and Shutdown Circuitry

• Pb-Free Packaging Designated by Suffix Code EP
