Li-Ion Battery Charger

ADP3806

FEATURES

GENERAL DESCRIPTION

Li-Ion Battery Charger

The ADP3806 is a complete Li-Ion battery-charging IC. The

device combines high output voltage accuracy with constant

current control to simplify the implementation of Constant-

Current, Constant-Voltage (CCCV) chargers. The ADP3806 is

available in three options. The ADP3806-12.6 guarantees the

final battery voltage be selected to 12.6 V or 16.8 V 0.6%, the

ADP3806-12.5 guarantees 12.525 V/16.7 V 0.6% and the

ADP3806 is adjustable using two external resistors to set the

battery voltage. The current sense amplifier has rail-to-rail

inputs to accurately operate under low drop out and short circuit

conditions. The charge current is programmable with a dc

voltage on ISET. A second differential amplifier senses the system

current across an external sense resistor and outputs a linear

voltage on the ISYS pin. The bootstrapped synchronous driver

allows the use of two NMOS transistors for lower system cost.
