MAX8900A/MAX8900B/MAX8900C
1.2A Switch-Mode Li+ Chargers with ±22V Input
Rating and JEITA Battery Temperature Monitoring
General Description
The MAX8900_ is a high-frequency, switch-mode char-
ger for a 1-cell lithium ion (Li+) or lithium polymer
(Li-Poly) battery. It delivers up to 1.2A of current to the
battery from 3.4V to 6.3V (MAX8900A/MAX8900C) or
3.4V to 8.7V (MAX8900B). The 3.25MHz switch-mode
charger is ideally suited to small portable devices such
as headsets and ultra-portable media players because it
minimizes component size and heat.
Several features make the MAX8900_ perfect for high-
reliability systems. The MAX8900_ is protected against
input voltages as high as +22V and as low as -22V.
Battery protection features include low voltage prequali-
fication, charge fault timer, die temperature monitoring,
and battery temperature monitoring. The battery temper-
ature monitoring adjusts the charge current and termina-
tion voltage as described in the JEITA* specification for
safe use of secondary lithium-ion batteries.
Charge parameters are easily adjustable with external
components. An external resistance adjusts the charge
current from 50mA to 1200mA. Another external resis-
tance adjusts the prequalification and done current
thresholds from 10mA to 200mA. The done current thresh-
old is very accurate achieving Q 1mA at the 10mA level.
The charge timer is adjustable with an external capacitor.
The MAX8900_ is available in a 0.4mm pitch, 2.44mm x
2.67mm x 0.64mm WLP package.
