ADIMAX22203ATU+
Overview
The MAX22203ATU+ is a dual 65V, 3.8A brushed DC motor driver featuring integrated current sensing and regulation. It provides two independent half-bridges that can be configured to drive one or two brushed DC motors, or a single stepper motor, with a wide supply range from 4.5V to 65V.
Why Choose This Part
This driver eliminates the need for external power-sense resistors by integrating current sensing, which reduces board space and BOM cost. It offers high efficiency with low-power sleep modes (20uA typical) and robust protection features including overcurrent, undervoltage lockout, and thermal shutdown.
Applications
Key Specifications
Getting Started
To evaluate this driver, engineers typically use the MAX22203EVKIT, which provides a complete hardware platform to test PWM control and current regulation. Design involves connecting PWM-compatible logic to the input pins and configuring the current-limit threshold via external resistors.
