17550

Quad H-Bridge Micromotor Driver

with DC/DC Boost Converter

QUAD H-BRIDGE MICROMOTOR

DRIVER WITH DC/DC BOOST

CONVERTER

The 17550 is a monolithic quad H-Bridge power IC ideal for portable

electronic applications containing tiny bipolar stepper motors and/or brush

DC-motors powered by two-to-four cell NiCd/NiMH batteries.

The 17550 operates from 2.5 V to 5.5 V, with independent control of each

H-Bridge via parallel 3.0 V or 5.0 V logic-compatible I/O. The device features

an on-board DC/DC boost converter that allows motor operation all the way

down to 1.6 V (the boost converter supplies the gate-drive voltage for each of

the four independent H-bridge output stages). Each output bridge has its own

gate-drive and logic circuitry with built-in shoot-through current protection.

The 17550 has four operating modes: Forward, Reverse, Brake, and

Tri-Stated (High Impedance). The 17550 has a low total R_DS(ON)of 1.2 Ω max

@ 25°C. In addition, it can be set into a very low current-drain standby mode.

The H-Bridge outputs can be independently PWM’ed at up to 200 kHz for

speed/torque and current control. The 17550 can efficiently drive many types

of micromotors owing to its low output resistance and high output slew rates.
