MAX8808XETA

The MAX8808XETA intelligent, stand-alone constant-current/constant-voltage (CCCV), thermally regulated linear chargers are designed for charging a single-cell lithium-ion (Li+) battery. The MAX8808XETA integrate the current sense circuit, MOS pass element, and thermal-regulation circuitry, and eliminate the reverse-blocking schottky diode to create the simplest and smallest charging solution for handheld equipment.

Features of the MAX8808XETA are:(1)stand-alone linear 1-cell li+ battery charger;(2)no external fet, reverse blocking diode, or current-sense resistor required;(3)programmable fast-charge current (1a max);(4)proprietary die temperature regulation control;(5)+4.25v to +15v input voltage range with input ovp above +7v;(6)charge-current monitor for fuel gauging;(7)low dropout voltage.300mv at 500ma;(8)input power-source detection output (acok) and charge-enable input (en or en);(9)soft-start limits inrush current;(10)charge-status output (chg) for led or microprocessor (p) interface;(11):tiny 2mm x 2mm 8-pin tdfn package, 0.8mm (max) height.Applications of the MAX8808XETA are:(1)cellular and cordless phones;(2)smartphones and PDAs;(3)digital still cameras and MP3 players;(4)USB appliances;(5)charging cradles and docks;(6)bluetooth equipment.
