MAX4820/MAX4821
3.3V/+5V, 8-Channel, Cascadable Relay Drivers
with Serial/Parallel Interface
is shifted through all the MAX4820s in series. When CS
goes high, all outputs update simultaneously.
The MAX4820 can also be used in a slave configuration
that allows the user to address individual devices.
Connect all the DIN pins together, and use the CS input
to address one device at a time. Drive CS low to select
a slave and input the data into the shift register. Drive
CS high to latch the data and turn on the appropriate
outputs. Typically, in this configuration only one slave is
addressed at a time.
Inductive Kickback Protection
The MAX4820/MAX4821 feature built-in inductive kick-
back protection to reduce the voltage spike on OUT_
generated by a relay’s coil inductance when the output
is suddenly switched off. Internal diodes connected
from each output to COM allow the inductor current to
flow back to the supply. Connect the common cathode
(COM) of the internal protection diodes to V CC .
COM also can be connected to a higher voltage than
V CC (+6V max) for faster kickback recovery. In this con-
figuration, bypass COM to PGND with a 0.1μF capacitor.
