MAX1508/MAX1508Y/MAX1508Z 19-2890; Rev 2; 8/05 EVAALVUAAILTAIOBNLEKIT Linear Li+ Battery Charger with Integrated Pass FET, Thermal Regulation, and ACOK in 3mm x 3mm TDFN General Description The MAX1508 is an intelligent, stand-alone constant-current, constant-voltage (CCCV), thermally regulated linear charger for a single-cell lithium-ion (Li+) battery. The MAX1508 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 MAX1508 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. The MAX1508Y and MAX1508Z eliminate the prequalification state to allow startup into a load without a battery. Proprietary thermal-regulation circuitry limits the die temperature to +100°C when fast charging or while expos...
