1A Linear Li+ Battery Chargers with Integrated Pass
FET and Thermal Regulation in 2mm x 2mm TDFN
General Description
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.
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.
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

MARK
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/
MAX8808X ETA+ 8 TDFN-EP* 2mm x 2mm (T822-1)
MAX8808Y ETA+ 8 TDFN-EP* 2mm x 2mm (T822-1)
MAX8808Z ETA+ 8 TDFN-EP* 2mm x 2mm (T822-1)
