MAX4824ETP+
+3.3V/+5V, 8-Channel Relay Drivers with Fast Recovery Time and Power-Save Mode, TQFN20, Maxim, RoHS
The MAX4824 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 2.7? (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 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.
