MAX22200ETJ+T

Overview

The MAX22200ETJ+T is an eight-channel, 36V serial-controlled solenoid and motor driver manufactured by Analog Devices Inc./Maxim Integrated. It features low-impedance push-pull output stages with a typical resistance of 200mΩ per channel, supporting up to 1A RMS drive current. The device utilizes a Serial Peripheral Interface (SPI) for control and supports daisy-chain configurations. Each half-bridge can be configured as a high-side or low-side driver, paired for doubled current, or arranged into full bridges to drive four latching valves or brushed DC motors. It incorporates Voltage Drive Regulation (VDR) and Current Drive Regulation (CDR) methods alongside comprehensive protection and diagnostic capabilities.

Feature Summary

• Integrates eight independent channels with low-impedance push-pull outputs capable of sourcing and sinking up to 1A RMS current per channel.
• Supports flexible half-bridge configurations including high-side, low-side, parallel current doubling, and full-bridge setups for dual-stable valves or brushed DC motors.
• Features integrated Voltage Drive Regulation (VDR) and Current Drive Regulation (CDR) for precise load control.
• Includes robust protection mechanisms and diagnostic reporting accessible via the SPI interface.

Applications

• Driving multiple solenoids in industrial automation systems
• Controlling dual-stable latching valves in fluid management applications
• Actuating brushed DC motors in compact motion control modules

Procurement Notes

Verify the specific suffix 'ETJ' against the manufacturer's official datasheet to confirm package type and temperature range specifications. Ensure that the ordering information matches the exact part number variant required for your design, as suffixes may denote differences in packaging or thermal characteristics. Cross-reference the component details with the latest Analog Devices documentation to confirm availability and compliance status prior to procurement.

Selection Notes

Select this component when designing systems requiring independent control of multiple high-current loads within a space-constrained environment. The integrated SPI interface and daisy-chain capability simplify board routing compared to parallel control schemes. Consider the VDR and CDR features if precise current limiting or voltage regulation across varying load impedances is necessary. Evaluate the thermal performance requirements given the 32-pin TQFN package and the potential for simultaneous channel activation.

Part Context

The MAX22200 series belongs to Maxim Integrated's portfolio of intelligent power switches and motor drivers designed for automotive and industrial applications. This specific model focuses on multi-channel solenoid actuation, offering a high degree of integration by combining power stage drivers with digital control logic. It addresses the need for compact, reliable solutions in applications where space is limited but multiple independent actuator controls are required.

Replacement Considerations

Consult the official Analog Devices product selector guide for verified cross-reference part numbers. Check for alternative models within the MAX22200 family or other multi-channel driver series that match the required voltage, current, and interface specifications before substituting components.
