+3.3V/+5V, 8-Channel Relay Drivers with Fast

Recovery Time and Power-Save Mode

General Description

Features

♦ Built-In Zener Kickback Protection for Fast

The MAX4822–MAX4825 8-channel relay drivers offer

built-in kickback protection and drive +3V/+5V non-

latching 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) quies-

cent current and have 1µA output off-leakage current.

A Zener-kickback-protection circuit significantly

reduces recovery time in applications where switching

speed is critical.

Recovery

♦ Programmable Power-Save Mode Reduces Relay

Power Consumption (MAX4822/MAX4824)

♦ 10MHz SPI-/QSPI-/MICROWIRE-Compatible Serial

Interface

♦ Eight Independent Output Channels

♦ Drive +3V and +5V Relays

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. This mode keeps the relay activated while

significantly reducing the power consumption.

♦ Guaranteed 70mA (min) Coil Drive Current

♦ Guaranteed 5Ω (max) R

♦ SET / RESET Functions to Turn On/Off All

Outputs Simultaneously

The MAX4822/MAX4823 feature a 10MHz SPI™-/

QSPI™-/MICROWIRE™-compatible serial interface.

Input data is shifted into a shift register and latched to

the outputs when CS transitions from low to high. Each

data bit in the shift register corresponds to a specific

output, allowing independent control of all outputs.

♦ Serial Digital Output for Daisy Chaining

♦ Optional Parallel Interface (MAX4824/MAX4825)

♦ Low 300µA (max) Quiescent Supply Current

♦ Space-Saving, 4mm x 4mm, 20-Pin TQFN Package

The MAX4824/MAX4825 feature a 4-bit parallel-input

interface. The first 3 bits (A0, A1, A2) determine the out-

put address, and the fourth bit (LVL) determines whether

the selected output is switched on or off. Data is latched

to the outputs when CS transitions from low to high.

Ordering Information

PIN-

PACKAGE

CODE

The MAX4822–MAX4825 feature separate set and reset

functions, allowing turn-on or turn-off of all outputs

simultaneously with a single control line. Built-in hys-

teresis (Schmidt trigger) on all digital inputs allows

these devices to be used with slow-rising and falling

signals, such as those from optocouplers or RC power-

up initialization circuits. The MAX4822–MAX4825 are

available in space-saving 4mm x 4mm, 20-pin thin QFN

packages. They are specified over the -40°C to +85°C

extended temperature range.
