MAX4822ETP+

Overview

The MAX4822ETP+ is an eight-channel relay driver manufactured by Analog Devices Inc./Maxim Integrated. It operates with a supply voltage range of 2.3V to 5.5V and delivers up to 70mA output current per channel. The device features fast recovery capabilities and utilizes a 20-pin TQFN package (4x4 mm). It supports +3.3V/+5V logic inputs and includes integrated flyback diodes for inductive load protection.

Feature Summary

• Eight independent N-channel power switch outputs
• Integrated flyback diodes for inductive load protection
• Fast recovery time for rapid switching operations
• Compatible with standard +3.3V and +5V logic levels

Applications

• Industrial control systems requiring multiple relay actuation
• Automotive electronic modules
• Aerospace instrumentation panels

Procurement Notes

Verify the specific suffix ETP against official Analog Devices documentation to confirm the 20-TQFN package and tube packaging configuration. Ensure compatibility with the required 2.3V to 5.5V supply range and 70mA current rating for the target application design.

Selection Notes

Select this component when designing circuits requiring simultaneous control of up to eight relays from a single microcontroller interface. The integrated protection diodes simplify board layout by eliminating external components, while the compact TQFN footprint aids in space-constrained industrial and automotive designs.

Part Context

This part belongs to the Maxim Integrated family of power drivers designed for robust operation in demanding environments. It serves as a bridge between low-power digital logic and higher-current inductive loads, providing reliable switching performance for critical system components in professional electronics applications.

Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Generic equivalents may lack the specific fast recovery characteristics or integrated protection features documented for this model.
