MAX4822 - (MAX4822 - MAX4825) 8-Channel Relay Drivers

Datasheet Summary

Description

The MAX4822

MAX4825 8-channel relay drivers offer built-in kickback protection and drive +3V/+5V nonlatching or dual-coil-latching relays.

Features

  • a 2.7Ω (typ) on-resistance and is guaranteed to sink 70mA (min) of load current. These devices consume less than 300µA (max) quiescent current and have 1µA output off-leakage current. A Zener-kickback-protection circuit significantly reduces recovery time in.

19-3789; Rev 0; 8/05 +3.3V/+5V, 8-Channel Relay Drivers with Fast Recovery Time and Power-Save Mode General Description The MAX4822–MAX4825 8-channel relay drivers offer built-in kickback protection and drive +3V/+5V nonlatching or dual-coil-latching relays. Each independent open-drain output features a 2.7Ω (typ) on-resistance and is guaranteed to sink 70mA (min) of load current. These devices consume less than 300µA (max) quiescent current and have 1µA output off-leakage current. A Zener-kickback-protection circuit significantly reduces recovery time in applications where switching speed is critical. The MAX4822/MAX4824 feature a unique power-save mode where the relay current, after activation, can be reduced to a level just above the relay hold-current threshold.
