MAX4821EUP+ General Description

The MAX4820/MAX4821 8-channel relay drivers offer built-in kickback protection and drive +3.3V/+5V nonlatching or dual-coil-latching relays. These devices are especially useful when driving +3V relays. Each independent open-drain output features a 2Ω on-resistance and is guaranteed to sink 70mA (min) of load current. Both devices consume less than 50µA (max) quiescent current and have 1µA output off-leakage current.

Key Features

8 Independent Output Channels
Built-In Inductive Kickback Protection
Drive +3V and +5V Relays
Guaranteed 70mA (min) Coil Drive Current
Active-Low SET Function to Turn On All Outputs Simultaneously
Active-Low RESET Function to Turn Off All Outputs Simultaneously
SPI-/QSPI-/MICROWIRE-Compatible Serial Interface (MAX4820)
Serial Digital Output for Daisy Chaining (MAX4820)
Parallel Interface (MAX4821)
Low 50µA (max) Quiescent Supply Current
Space-Saving 20-Pin Thin QFN Package

Application

Automated Test Equipment (ATE)
Central Office
DSL, ADSL Line Cards
E1/T1 Redundancy
Industrial Equipment
