Overview
19-3670; Rev 0; 4/05 KIT ATION EVALU E L B AVAILA 1A Linear Li+ Battery Chargers with Integrated Pass FET and Thermal Regulation in 2mm x 2mm TDFN General Description The MAX8808X/MAX8808Y/MAX8808Z intelligent, stand-alone constant-current/constant-voltage (CCCV), thermally regulated linear chargers are designed for charging a single-cell lithium-ion (Li+) battery.
The MAX8808X/MAX8808Y/MAX8808Z 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.
The MAX8808X functions as a stand-alone charger to control the charging sequence from the prequalification state through fast-charge, top-off charge, and fullcharge indication.
The MAX8808Y and MAX8808Z eliminate the prequalification state to allow startup into a load without a battery.
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 MAX8808X/MAX8808Y/MAX8808Z achieve high flexibility by providing an adjustable fast-charge current with an external resistor.
Other features include a battery charging-status indicator (CHG), an active-low conwww.

com trol input ( EN ) for the MAX8808X and MAX8808Z (active-high control input for the MAX8808Y), and an active-low input power-source detection output (ACOK).
The MAX8808X/MAX8808Y/MAX8808Z accept a +4.
25V to +15V supply, but disable charging when the input voltage exceeds +7V to protect against unqualified or faulty AC adapters.
The MAX8808X/MAX8808Y/ MAX8808Z operate over the extended temperature range (-40°C to +85°C) and are available in a compact 8-pin thermally enhanced 2mm x 2mm TDFN package with 0.
8mm (max) height.
