Linear Li+ Battery Charger with Integrated Pass FET,

Thermal Regulation, and ACOK in 3mm x 3mm TDFN

General Description

Features

The MAX1508 is an intelligent, stand-alone constant-cur-

rent, 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 elimi-

nates the reverse-blocking Schottky diode, to create the

simplest and smallest charging solution for hand-held

equipment.

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

♦ No External FET, Reverse-Blocking Diode, or

Current-Sense Resistor Required

♦ Programmable Fast-Charge Current (0.8A max)

♦ Proprietary Die-Temperature Regulation Control

(+100°C)

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.

♦ +4.25V to +13V Input Voltage Range with Input

Overvoltage Protection (OVP) Above +7V

♦ Charge-Current Monitor for Fuel Gauging

♦ Low Dropout Voltage—130mV at 0.425A

Proprietary thermal-regulation circuitry limits the die

temperature to +100°C when fast charging or while

exposed to high ambient temperatures, allowing maxi-

mum charging current without damaging the IC.

♦ Input Power-Source Detection Output (ACOK) and

Charge-Enable Input (EN)

♦ Soft-Start Limits Inrush Current

The MAX1508 achieves high flexibility by providing an

adjustable fast-charge current by an external resistor.

Other features include the charging status (CHG) of the

battery, an active-low control input (EN), and an active-

low-input power-source detection output (ACOK).

♦ Charge Status Output (CHG) for LED or

Microprocessor Interface

♦ Small 3mm x 3mm 8-Pin Thin DFN Package,

0.8mm High

The MAX1508 accepts a +4.25V to +13V supply, but dis-

ables charging when the input voltage exceeds +7V to

protect against unqualified or faulty AC adapters. The

MAX1508 operates over the extended temperature

range (-40°C to +85°C) and is available in a compact

8-pin thermally enhanced 3mm x 3mm thin DFN pack-

age with 0.8mm height.
