MAX22203AUU+T

Overview

The MAX22203AUU+T is a dual H-bridge motor driver device intended for driving bipolar stepper motors and brushed DC motors. It integrates the functions needed to interface a microcontroller or motion controller to motor windings, providing a compact solution for two-motor or single-stepper applications. The part is used where a small, integrated dual-bridge solution simplifies board design and motor interfacing.

Why Choose This Part

Choosing this integrated dual H-bridge reduces component count and PCB area compared with discrete MOSFET H-bridges, simplifying BOM and layout. It is a convenient option when you need two motor channels (or one bipolar stepper channel) in a single package and want a straightforward interface to a microcontroller or motion controller. The integrated approach speeds development and helps ensure matching between bridge halves.

Applications

Getting Started

Start by reading the manufacturer's datasheet and any available evaluation or reference board documentation to learn recommended power decoupling, layout, and thermal considerations. If Analog Devices/Maxim provides an evaluation kit or reference design, use that to verify wiring and control signals; otherwise prototype on a breakout or carrier board. Use a current-limited bench supply and an oscilloscope to verify motor drive waveforms and to set any required current-sensing or limiting components.
