General Description
The MAX20366 evaluation kit (EV kit) is a fully assembled
and tested circuit board that demonstrates the MAX20366
ultra-low power wearable power management integrated
circuit (PMIC). The MAX20366 includes voltage regulators
such as bucks, boost, buck-boost, and linear regulators,
and a complete battery management solution with battery
seal, charger, power path, and fuel gauge.
The device is configurable through an I
allows for programming various functions and reading
device status. The EV kit GUI application sends
commands to the MAXPICO2PMB# adapter board to
configure the device.
The MAX20366EVKIT# has no harvester feature. The
MAX20366HEVKIT# has a harvester feature enabled and
can be connected to MAX20361EVKIT# to evaluate the
interaction between the two devices.
