MAX8900AEVKIT

Evaluation Kit for the MAX8900A and MAX8900B


Please check latest availability status for a specific part variant.

Description

The MAX8900A evaluation kit (EV kit) is a fully assembled and tested circuit for evaluating the MAX8900A switch-mode Li+/Li-Poly charger with ±22V input rating and JEITA* battery temperature monitoring. The MAX8900A charges a 1-cell lithium-ion (Li+) or lithium-polymer (Li-Poly) battery. The MAX8900A delivers up to 1.2A of current to the battery from a 3.4V to 6.3V supply. External resistors and potentiometers adjust the fast-charge current and the prequalification and done current thresholds. A JEITA battery temperature monitor adjusts charge current and termination voltage.

The MAX8900A EV kit comes with the MAX8900A installed, but can also be used to evaluate the MAX8900B with IC replacement of U1. Request a free sample of the MAX8900B when you order the MAX8900A EV kit.
