MAX22200ETJ+

Overview

The MAX22200ETJ+ is an eight-channel, 36V integrated serial control solenoid and motor driver manufactured by Analog Devices Inc./Maxim Integrated. It features low-impedance push-pull output stages with a typical on-resistance of 200mΩ per channel. The device supports continuous output currents up to 1A RMS and offers flexible half-bridge configurations for low-side, high-side, parallel, or full-bridge driving modes. Control is managed via a Serial Peripheral Interface (SPI) supporting daisy-chain topologies at speeds up to 10MHz. It includes Voltage Drive Regulation (VDR) and Current Drive Regulation (CDR) capabilities, comprehensive protection mechanisms, and diagnostic registers. The component is housed in a compact 5mm x 5mm, 32-pin TQFN package and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Eight independent channels with low on-resistance push-pull outputs for efficient power delivery
• Flexible bridge configuration support enabling single-ended, parallel, or full-bridge driving modes
• Integrated SPI interface with daisy-chain capability for simplified multi-device system control
• Advanced diagnostic and protection features including overcurrent, open-load, and thermal shutdown

Applications

• Solenoid valve drivers in industrial automation systems
• Brushed DC motor control in embedded applications
• Latching valve actuation in fluid control modules
• Multi-axis motion control subsystems requiring compact integration

Procurement Notes

Verify the specific suffix 'ETJ+' against the manufacturer's official ordering guide to confirm package type and tape-and-reel specifications. Ensure compatibility with the required operating voltage range and thermal management requirements for the target application environment. Cross-reference the datasheet revision date to confirm current design parameters and compliance status before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring multiple isolated or semi-isolated loads driven from a single controller. Evaluate the need for current regulation versus voltage regulation based on load characteristics. Consider the thermal dissipation requirements given the 1A RMS rating and ensure adequate PCB copper area for heat spreading. Confirm that the SPI bus speed and daisy-chain topology fit within the system's timing constraints.

Part Context

This part belongs to the Maxim Integrated family of intelligent motor and solenoid drivers, designed to reduce system complexity by integrating power stages and control logic. It complements other devices like the MAX22203 for higher current applications or the SC2200 series for RF functions. The MAX22200ETJ+ specifically targets cost-sensitive, space-constrained designs needing moderate current handling with precise digital control.

Replacement Considerations

Check for direct pin-to-pin replacements such as the MAX22200AETJ+ which may offer enhanced diagnostic register clearing features. Verify functional equivalence regarding drive current, voltage ratings, and interface protocols before substitution. Consult the manufacturer's obsolescence notices and recommended replacement lists for any discontinued variants.
