Advance Information

Quad H-Bridge Micromotor

Driver with DC/DC Boost

Converter

17550

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.

H-BRIDGE MOTOR DRIVER

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.

EV SUFFIX (Pb-FREE)

98ASA10591D

36-TERMINAL VMFP

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.
