Evaluation Kit for the MAX8814 (MAX8814EVKIT) (MAX8814EVKIT)

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 resistor (R2). Other features include an active-low control input (active-low EN) and an active-low input power source detection output (active-low POK). The IC also features a booting assistant circuit that distinguishes input sources and battery connection and provides an output signal (ABO) for system booting.
