1A Linear Li+ Battery Chargers with Integrated Pass

FET and Thermal Regulation in 2mm x 2mm TDFN

General Description

Features

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 cur-

rent-sense circuit, MOS pass element, and thermal-reg-

ulation circuitry, and eliminate the reverse-blocking

Schottky diode to create the simplest and smallest

charging solution for handheld equipment.

♦ Stand-Alone Linear 1-Cell Li+ Battery Charger

♦ No External FET, Reverse Blocking Diode, or

Current-Sense Resistor Required

♦ Programmable Fast-Charge Current (1A max)

♦ Proprietary Die Temperature Regulation Control

(+115°C)

♦ +4.25V to +15V Input Voltage Range with Input

OVP Above +7V

The MAX8808X 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 MAX8808Y and MAX8808Z elimi-

nate 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 maxi-

mum charging current without damaging the IC.

♦ Charge-Current Monitor for Fuel Gauging

♦ Low Dropout Voltage—300mV at 500mA

♦ Input Power-Source Detection Output (ACOK) and

Charge-Enable Input (EN or EN)

♦ Soft-Start Limits Inrush Current

♦ Charge-Status Output (CHG) for LED or

Microprocessor (µP) Interface

The MAX8808X/MAX8808Y/MAX8808Z achieve high

flexibility by providing an adjustable fast-charge current

with an external resistor. Other features include a bat-

tery charging-status indicator (CHG), an active-low con-

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).

♦ Tiny 2mm x 2mm 8-Pin TDFN Package, 0.8mm

(max) Height

PIN-PACKAGE

The MAX8808X/MAX8808Y/MAX8808Z accept a

+4.25V to +15V supply, but disable charging when the

input voltage exceeds +7V to protect against unquali-

fied 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.
