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.
