MAX22203ATU+

Overview

The MAX22203ATU+ is a dual H-bridge motor driver designed for brush DC and stepper motors. It supports supply voltages from 4.5V to 65V with a maximum pulse current of 3.8A per bridge. The device features integrated current sensing, adjustable current drive regulation, and multiple decay modes. Typical total on-resistance is 0.3Ω. Logic inputs operate at 1.8V thresholds, and the unit includes overcurrent protection, thermal shutdown, and undervoltage lockout.

Feature Summary

Dual H-bridge architecture supporting independent control of two brushed DC motors or one stepper motor
Integrated non-dissipative current sensing with adjustable current drive regulation and configurable fixed off-time
Supports slow, mixed, and fast decay modes for precise motor control
Comprehensive protection mechanisms including overcurrent protection, thermal shutdown, and undervoltage lockout

Applications

Brushed DC motor control systems
Stepper motor driving applications
Industrial automation actuators
Small capacitor load driving

Procurement Notes

Verify the complete part number MAX22203ATU+ against official Analog Devices documentation to ensure correct package identification as 38-TQFN (5x7). Confirm that the suffix indicates lead-free compliance and RoHS status. Cross-reference the manufacturer's latest datasheet for any potential product changes or obsolescence notices prior to finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring high voltage operation up to 65V and efficient power management. The low on-resistance minimizes heat generation, while the integrated current sensing eliminates external shunt resistors. Ensure the application PCB layout accommodates the required thermal dissipation for RMS currents, considering factors like ground planes and forced ventilation.

Part Context

This device belongs to the MAX22203 series of intelligent motor drivers from Analog Devices/Maxim Integrated. It integrates control logic and power stages into a single CMOS solution. The family is characterized by compact packaging and robust diagnostic capabilities, targeting applications where space constraints and system reliability are critical design parameters.
