MAX8900A Evaluation Kit
Evaluates: MAX8900A/MAX8900B
General Description
Features
S 3.25MHz Switching Li+/Li-Poly Battery Charger
The MAX8900A evaluation kit (EV kit) is a fully assembled
and tested circuit for evaluating the MAX8900A switch-
mode Li+/Li-Poly charger with ±±±V inꢀut rating and
JEITA* battery temꢀerature monitoring. The MAX8900A
charges a 1-cell lithium-ion (Li+) or lithium-ꢀolymer
(Li-Poly) battery. The MAX8900A delivers uꢀ to 1.±A of
current to the battery from a 3.4V to 6.3V suꢀꢀly. External
resistors and ꢀotentiometers adjust the fast-charge
current and the ꢀrequalification and done current thresh-
olds. A JEITA battery temꢀerature monitor adjusts
charge current and termination voltage.
