The MAX8900_ is a high-frequency, switch-mode charger
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) 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 highreliability
systems. The MAX8900_ is protected against
input voltages as high as +22V and as low as -22V.
Battery protection features include low voltage prequalification,
charge fault timer, die temperature monitoring,
and battery temperature monitoring. The battery temperature
monitoring adjusts the charge current and termination
voltage as described in the JEITA* specification for
safe use of secondary lithium-ion batteries.
