+3.3V/+5V, 8-Channel, Cascadable Relay Drivers

with Serial/Parallel Interface

0/MAX4821

General Description

Features

The MAX4820/MAX4821 8-channel relay drivers offer

built-in kickback protection and drive +3.3V/+5V non-

latching or dual-coil-latching relays. These devices are

especially useful when driving +3V relays. Each inde-

pendent 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.

♦ 8 Independent Output Channels

♦ Built-In Inductive Kickback Protection

♦ Drive +3V and +5V Relays

♦ Guaranteed 70mA (min) Coil Drive Current

♦ SET Function to Turn On All Outputs

Simultaneously

The MAX4820 features an SPI™-/QSPI™-/MICROWIRE™-

compatible serial interface. Input data is shifted into an 8-

bit shift register and latched to the outputs when CS

transitions from low to high. Each data bit in the shift reg-

ister corresponds to a specific output, allowing indepen-

dent control of all outputs.

♦ RESET Function to Turn Off All Outputs

Simultaneously

♦ SPI-/QSPI-/MICROWIRE-Compatible Serial

Interface (MAX4820)

♦ Serial Digital Output for Daisy Chaining

The MAX4821 features a 4-bit (A0, A1, A2, LVL) paral-

lel-input interface. The first three bits (A0, A1, A2) deter-

mine the output address, and the fourth bit (LVL)

determines whether the selected output is switched on

or off. Data is latched to the outputs when CS transi-

tions from low to high.

(MAX4820)

♦ Parallel Interface (MAX4821)

♦ Low 50µA (max) Quiescent Supply Current

♦ Space-Saving 20-Pin Thin QFN Package

Both devices feature separate set and reset functions

that allow the user to turn on or turn off all outputs simul-

taneously with a single control line. Built-in hysteresis

(Schmidt trigger) on all digital inputs allows this device

to be used with slow rising and falling signals, such as

those from optocouplers or RC power-up initialization

circuits. The MAX4820/MAX4821 are available in 20-pin

TSSOP and space-saving 20-pin Thin QFN packages.
