High Input Voltage Charger With Power

Path Management

The ISL9301 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

accepts an input voltage up to 28V but is disabled when the

input voltage exceeds 10.5V OVP threshold. The 28V rating

eliminates the overvoltage protection circuit required in a

low-voltage charger. The charge current and the

end-of-charge (EOC) current are programmable with

external resistors. When the battery voltage is lower than

2.8V, the charger preconditions the battery with 16% of the

programmed charge current. When the charge current

reduces to the programmable EOC current level during the

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

logic LOW to indicate the end-of-charge condition. The

charger will continue to charge until the user programmed

timeout interval has elapsed, then the charger is terminated.

The ISL9301 uses separate power paths to supply the

system load and charge 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

with the input source, thus minimizing unnecessary

charge/discharge cycles and improving the battery life.

Two indication pins (PPR and CHG) allow simple interface to

a microprocessor or LEDs.
