MAX8814 Evaluation Kit

Evluates:MAX814

General Description

Features

♦ CCCV, Thermally Regulated Linear 1-Cell Li+

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.

Battery Charger

♦ No External MOSFET, Reverse Blocking Diode, or

Current-Sense Resistor

♦ Programmable Fast-Charge Current (1A

max)

RMS

♦ Proprietary Die Temperature Regulation Control

(+115°C)

♦ 4.25V to 28V Input Voltage Range with Input OVP

Above 7V

♦ Charge-Current Monitor for Fuel Gauging (ISET)

♦ Low Dropout Voltage (300mV at 500mA)

♦ Input Power-Source Detection Output (POK) and

Charge-Enable Input (EN)

Ordering Information

♦ Soft-Start Limits Inrush Current

♦ Output for Autobooting (ABO)

♦ Fully Assembled and Tested
