General Description

The MAX1507 is an intelligent, stand-alone constant-cur-

rent, constant-voltage (CCCV), thermally regulated linear

charger for a single-cell lithium-ion (Li+) battery. The

MAX1507 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.

The MAX1507 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.

Proprietary thermal-regulation circuitry limits the die

temperature when fast charging or while exposed to

high ambient temperatures, allowing maximum charg-

ing current without damaging the IC.

The MAX1507 achieves high flexibility by providing an

adjustable fast-charge current and thermal regulation

setpoints. Other features include the charging status

(CHG) of the battery and an active-low control input (EN).

The MAX1507 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

MAX1507 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.
