The MAX1501 evaluation kit (EV kit) is a complete, fully assembled and tested circuit board that demonstrates the highly integrated MAX1501 linear battery charger for a single-cell lithium-ion (Li+) or a 3-cell NiMH/NiCd battery. The EV kit safely charges a single Li+ battery to 4.1V or 4.2V or a 3-cell NiMH/NiCd to 4.5V or 4.95V (4.95V must collaborate with the microprocessor control). The EV kit accepts a power-supply input of 4.5V to 13V, but disables charging when the input voltage exceeds 6.5V. Jumpers on the EV kit allow adjustments to the total charging time, battery voltage levels, top-off current, die temperature regulation levels, and charging modes. LEDs on the board indicate the status of the charging cycle.
