MAX22210ATJ+T

Overview

The MAX22210ATJ+T is a dual brushed DC or single stepper motor driver featuring two 36V, 3.8A half-bridges in a TSSOP-28 package. It operates on a supply voltage range of 4.5V to 36V with a maximum operating current of 3.8A. The device supports an extended temperature range from -40°C to +125°C and includes integrated non-dissipative current sensing, overcurrent protection, thermal shutdown, and under-voltage lockout.

Feature Summary

• Integrates two high-efficiency half-bridges with low on-resistance for reduced heat generation
• Features built-in non-dissipative current sensing to eliminate external power resistors
• Includes a 128-step microstepping indexer controlled via STEP/DIR interface
• Provides diagnostic outputs and fault indication through dedicated pins

Applications

• Brushed DC motor control systems
• Single stepper motor positioning applications
• Industrial automation actuators
• Motion control modules requiring compact form factors

Procurement Notes

Verify the specific suffix ATJ against official Analog Devices documentation to confirm pin compatibility and thermal characteristics. Ensure the procurement channel provides valid RoHS compliance certificates. Confirm availability status as distribution channels may indicate restricted supply. Validate that the component matches the required TSSOP-28 footprint for PCB integration.

Selection Notes

Select this component when designing systems requiring dual half-bridge capability within a small surface-mount package. It is suitable for applications needing precise current regulation without external sense resistors. Consider the thermal performance limits based on PCB layout and ambient conditions. Verify that the 36V rating aligns with the motor supply voltage requirements.

Part Context

This part belongs to the MAX22210 series of motor drivers manufactured by Analog Devices Inc./Maxim Integrated. The series focuses on providing integrated solutions for motion control with advanced features like microstepping and current monitoring. The ATJ variant specifically denotes the TSSOP-28 packaging option within this product family.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure any replacement maintains the same voltage ratings, current capabilities, and package dimensions.
