The MAX4211E evaluation kit (EV kit) is a fully assembled
and tested surface-mount circuit board that provides
overpower circuit-breaker and fault protection using the
MAX4211E power-monitoring IC. The EV kit demonstrates
the programmable overpower monitoring feature with
manual or microcontroller reset options of the MAX4211E.
The MAX4211E controls an external p-channel high-side
power MOSFET to provide overpower fault protection.
The MAX4211E EV kit’s circuit overpower threshold is
configured for 100W with a maximum input voltage of
20V and up to 5A of load current. This makes it suitable
for circuit-breaker applications in notebooks and other
portable power systems. The EV kit may be reconfig-
ured for other power thresholds with a maximum load
current of up to 10A.
The EV kit can also be used to evaluate other versions
of the MAX4211 power-monitoring ICs.
