MAX4821ETP+T

Power Distribution Switches, Load Drivers Overview

The MAX4821ETP+T is an eight-channel cascade relay driver manufactured by Analog Devices Inc./Maxim Integrated. It features a single input to eight output configuration with N-channel outputs capable of sourcing up to 70mA per channel. The device operates within a load voltage range of 2.3V to 5.5V and utilizes an SPI interface for control. Packaged in a 20-TQFN (4x4) surface-mount enclosure, it supports operating temperatures from -40°C to +85°C.

Power Distribution Switches, Load Drivers Feature Summary

Integrates eight independent N-channel power switches for relay or solenoid actuation
Utilizes serial peripheral interface (SPI) for digital control and status feedback
Supports cascaded operation for driving multiple channels from a single input signal

Power Distribution Switches, Load Drivers Applications

Industrial automation relay control systems
Telecommunications switching equipment
Test and measurement instrumentation

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'ETP' corresponds to the 20-TQFN package and tape-and-reel shipping format. Confirm RoHS compliance status through official documentation. Ensure the supplier provides valid traceability for the Analog Devices/Maxim Integrated brand. Cross-reference the manufacturer part number against current availability lists as supply conditions may vary.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when an application requires controlling multiple low-power loads such as relays or solenoids from a microcontroller via SPI. The 70mA output current per channel is suitable for standard industrial relay coils. Consider the 20-TQFN footprint for space-constrained PCB designs requiring surface-mount assembly.

Power Distribution Switches, Load Drivers Part Context

This device belongs to the MAX482x series of power drivers designed for high-density switching applications. It consolidates multiple discrete driver circuits into a single integrated solution, reducing board space and simplifying design complexity compared to using individual transistors or driver ICs for each channel.
