High Power Li-Ion Charger W/I-Path Management

ISL9230

The ISL9230 is a fully integrated high input voltage single-cell

Li-ion battery charger with power path management function.

This charger performs the CC/CV charge function required by

Li-ion batteries. The charger can withstand an input voltage up to

26V but is disabled when the input voltage exceeds 6.6V OVP

threshold. The input current limit and charge current are

programmable with external resistors. When the battery voltage

is lower than 3.0V, the charger preconditions the battery with

10% of the programmed charge current. When the charge

current reduces to the end-of-charge (EOC) current level during

the CV charge phase, the EOC indicator (CHG) will toggle to a

logic high to indicate the end-of-charge condition.

The ISL9230 uses separate power paths to supply the system

load and the battery. This feature allows the system to

immediately operate with a completely discharged battery. This

feature also allows the charge to terminate when the battery is

full while continuing to supply the system power from the input

source, thus minimizing unnecessary charge/discharge cycles

and prolonging the battery life.

Two indication pins (PG and CHG) allow simple interface to a

microprocessor or LEDs.
