MAX8814 Evaluation Kit
General Description
The MAX8814 evaluation kit (EV kit) is a fully assembled
and tested printed-circuit board (PCB) for evaluating
the MAX8814 28V linear Li+ battery charger. The
MAX8814 EV kit operates from an input supply range of
4.25V to 28V, but the IC disables charging if the input
voltage exceeds 7V to protect against unqualified or
faulty AC adapters. The MAX8814 EV kit features an
adjustable fast-charge current set by an external resis-
tor (R2). Other features include an active-low control
input ( EN ) and an active-low input power source detec-
tion output ( POK ). The IC also features a booting assis-
tant circuit that distinguishes input sources and battery
connection and provides an output signal (ABO) for
system booting.
