MAX1811

USB-Powered Li+ Charger

General Description

Features

The MAX1811 is a single-cell lithium-ion (Li+) battery

charger that can be powered directly from a USB port* or

from an external supply up to 6.5V. It has a 0.5% overall

battery regulation voltage accuracy to allow maximum

utilization of the battery capacity.

● Charges Single-Cell Li+ Batteries Directly from

USB Port

● 0.5% Overall Charging Accuracy

● Minimal External Components

● Input Diode Not Required

The charger uses an internal FET to deliver up to 500mA

charging current to the battery. The device can be

configured for either a 4.1V or 4.2V battery, using the

SELV input. The SELI input sets the charge current to

either 100mA or 500mA. An open-drain output (CHG)

indicates charge status.

● Automatic IC Thermal Regulation

● Preconditions Near-Depleted Cells

● Convenient Power SO-8 Package (1.4W)

Ordering Information

The MAX1811 has preconditioning that soft-starts a

near-dead battery cell before charging. Other safety

features include continuous monitoring of voltage and

current and initial checking for fault conditions before

charging.
