MAX22212ATJ+

Overview

The MAX22212ATJ+ is a single half-bridge motor driver from Analog Devices/Maxim Integrated. It integrates low impedance FETs with a typical on-resistance of 0.125 ohms (high side plus low side). The device supports an input voltage range of 4.5V to 36V and features embedded current drive regulation with adjustable chopping current and current limit shutdown time.

Feature Summary

• Integrates low impedance power FETs for efficient switching
• Includes embedded current drive regulation with adjustable parameters
• Provides integrated current detection outputs for monitoring

Applications

• Stepper motor drivers
• Brushed DC motor drivers
• Solenoid drivers
• Latching valve control

Procurement Notes

Verify the specific suffix ATJ against official datasheets to confirm package type and temperature rating. Confirm RoHS compliance status through manufacturer documentation. Check for obsolescence notices or lifecycle changes directly from Analog Devices before finalizing procurement plans.

Selection Notes

Select this component when a single half-bridge configuration is required for 36V systems. Consider the integrated current detection outputs if external ADC monitoring is needed. Evaluate the 0.125 ohm typical resistance against thermal requirements for the target load current.

Part Context

This part belongs to the MAX2221x series of motor drivers designed for industrial and automotive applications. It serves as a building block for more complex multi-phase motor control systems, often paired with other bridge drivers or controllers in motion control architectures.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure any replacement maintains the same half-bridge topology and voltage ratings.
