The MAX1507 is an intelligent, stand-alone constant-current, constant-voltage (CCCV), thermally regulated linear charger for a single-cell lithium-ion (Li+) battery. The MAX1507 integrates the current-sense circuit, MOS pass element, and thermal-regulation circuitry, and also eliminates the reverse-blocking Schottky diode to create the simplest and smallest charging solution for hand-held equipment.

The MAX1507 functions as a stand-alone charger to control the charging sequence from the prequalification state through fast-charge, top-off charge, and full-charge indication.

Proprietary thermal-regulation circuitry limits the die temperature when fast charging or while exposed to high ambient temperatures, allowing maximum charging current without damaging the IC.

The MAX1507 achieves high flexibility by providing an adjustable fast-charge current and thermal regulation setpoints. Other features include the charging status (active-low CHG) of the battery and an active-low control input (active-low EN).

The MAX1507 accepts a +4.25V to +13V supply, but disables charging when the input voltage exceeds +7V to protect against unqualified or faulty AC adapters. The MAX1507 operates over the extended temperature range (-40°C to +85°C) and is available in a compact 8-pin thermally enhanced 3mm x 3mm Thin DFN package with 0.8mm height.

Product Detail

The MAX1507/MAX1508 evaluation kit (EV kit) is a complete, fully assembled, and tested circuit board that demonstrates the MAX1507 linear battery charger for a single-cell lithium-ion (Li+) battery. To evaluate the MAX1508, U1 must be removed and replaced with a MAX1508 device. The EV kit safely charges a single Li+ battery to 4.2V. The EV kit accepts a power-supply input of 4.25V to 13V, but disables charging when the input voltage exceeds 7V. Jumpers on the EV kit allow adjustments to the die-temperature regulation levels (MAX1507 only) and the ability to disable the charger. An LED on the board indicates the status of the charging cycle.
