MAX22212AUI+T

Overview

The MAX22212AUI+T is a dual brushed DC or single stepper motor driver from Analog Devices. It integrates a high-current 36V, 7.6A MAX H-Bridge capable of driving one brushed DC motor or half of a stepper motor. The device supports four decay methods: slow, fast, and two mixed modes. It operates within a supply voltage range up to 36V and delivers a continuous current of 3.8A per channel.

Feature Summary

• Integrates a high-current 36V, 7.6A MAX H-Bridge for robust motor drive capability
• Supports multiple decay control methods including slow, fast, and mixed modes
• Designed for driving dual brushed DC motors or a single stepper motor

Applications

• Stepper motor drivers
• Brushed DC motor control systems
• Motion control applications

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the operating temperature range and package type match your design requirements. Check for AEC-Q100 qualification status if automotive reliability is required. Ensure compatibility with your system's voltage and current limits before procurement.

Selection Notes

Select this component for applications requiring integrated high-current motor driving without external power stages. Consider the 36V rating and 3.8A continuous current capability for medium-power motor loads. Evaluate the available decay modes for precise torque and noise control in motion control scenarios.

Part Context

This part belongs to the MAX2221x family of motor drivers from Maxim Integrated, now part of Analog Devices. These devices are designed to simplify motor control designs by integrating power stages and control logic into a compact package, reducing component count and board space.

Replacement Considerations

Check for direct pin-to-pin replacements within the MAX2221x series. Verify that alternative parts support the same 36V rating and current capabilities. Ensure interface compatibility and thermal performance meet original specifications.
