Datasheet
The MAX1894 evaluation kit (EV kit) is a fully assembled
and tested circuit board. It uses the MAX1894 lithium-
ion (Li+) battery-pack protector to protect four series
Li+ cell battery packs against overvoltage, undervolt-
age, excessive charge/discharge currents, and battery
pack-short conditions. Three external P-channel
MOSFETs control the charge and discharge paths of
the battery pack. The MAX1894 EV kit provides two
inputs, which can be used by a microcontroller (µC) to
control the protection MOSFETs or put the MAX1894 in
shutdown mode. The EV kit also evaluates the MAX1924.
