描述

The linear-mode evaluation kit (EV kit) is a complete battery charger for nickel metal hydride (NiMH) and "fast-charge" nickel-cadmium (NiCd) cells. The number of cells, charging current, and maximum charging time are selected by setting DIP switches. The board is easily tailored for the optimum charging parameters of a variety of "fast-charge" batteries, and can be used with either the MAX712 or MAX713.

The MAX712 EV kit automatically initiates the high- current, fast-charge cycle when batteries are installed into the holder. An LED indicates that the fast-charge sequence is in progress. Fast charge terminates when the maximum charging time has lapsed, or the circuit detects that full charge has been achieved, and/or if the temperature is beyond acceptable limits.

Thermistors are provided for optionally monitoring the battery temperature. The fast-charge cycle can be inhibited if the battery is too cold, or terminated if the battery temperature rises beyond limits. The temperature thresholds are adjustable using potentiometers on the board.
