The MAX1508ETA+T is a linear Li+ battery charger with integrated pass FET, thermal regulation and ACOK flag in 8 pin TDFN package. This device is an intelligent, stand-alone constant-current, constant-voltage (CCCV), thermally regulated linear charger for a single-cell lithium-ion (Li+) battery. It is integrated with current-sense circuit, MOS pass element, thermal-regulation circuitry and also eliminates the reverse-blocking Schottky diode to create the simplest and smallest charging solution for hand-held equipment. MAX1508 function as a stand-alone charger to control the charging sequence from the prequalification state through fast-charge, top-off charge and full-charge indication. It disables charging when the input voltage exceeds +7V to protect against faulty AC adapters.
