MAX4822ETP+T

Overview

The MAX4822ETP+T is an active power switch and relay driver manufactured by Analog Devices Inc./Maxim Integrated. It features a single input controlling eight N-channel outputs with a 1:8 ratio. The device operates within a temperature range of -40°C to +85°C and utilizes a surface-mount 20-TQFN (4x4) package. Typical on-resistance is specified at 2.7 Ohms, with an output current capacity of 70mA per channel. The component supports non-inverting input logic for direct interface compatibility.

Feature Summary

Integrates eight independent N-channel power switches driven by a single control input
Designed specifically for driving relays and solenoids in embedded systems
Utilizes a compact 20-pin TQFN surface-mount package for space-constrained PCB layouts

Applications

Relay driver circuits in industrial automation controllers
Solenoid actuation modules in home appliance control boards
Multi-channel power distribution switching in automotive electronics

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when sourcing components. Confirm that the manufacturer designation matches Analog Devices Inc. or Maxim Integrated to ensure authenticity. Check current availability status as supply chain conditions may affect lead times for this specific package variant.

Selection Notes

Select this component when a single control line must manage multiple high-side loads simultaneously. Ensure the application requires N-channel switching characteristics compatible with the 70mA output limit. Verify that the 2.7 Ohm on-resistance meets the voltage drop requirements for the connected load devices.

Part Context

This part belongs to the MAX4822 family of power distribution switches. It serves as a bridge between low-power digital logic and higher-current electromechanical actuators. The design simplifies board layout by consolidating multiple discrete driver transistors into a single integrated circuit solution.
