General Description
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.
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. The MAX1508Y and MAX1508Z elimi-
nate the prequalification state to allow startup into a load
without a battery.
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.
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
) for the
MAX1508 and MAX1508Z (active-high control input for
the MAX1508Y), and an active-low input power-source
detection output (
ACOK
).
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.
