Product Details

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, undervoltage, 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.
