ISL6294规格书详情
The ISL6294 is a cost-effective, fully integrated high input
voltage single-cell Li-ion battery charger. The charger uses a
CC/CV charge profile required by Li-ion batteries. The
charger accepts an input voltage up to 28V but is disabled
when the input voltage exceeds the OVP threshold, typically
6.8V, to prevent excessive power dissipation. The 28V rating
eliminates the overvoltage protection circuit required in a low
input voltage charger.
The charge current and the end-of-charge (EOC) current are
programmable with external resistors. When the battery voltage
is lower than typically 2.55V, the charger preconditions the
battery with typically 20 of the programmed charge current.
When the charge current reduces to the programmable EOC
current level during the CV charge phase, an EOC indication is
provided by the CHG pin, which is an open-drain output. An
internal thermal foldback function protects the charger from any
thermal failure.
Two indication pins (PPR and CHG) allow simple interface to
a microprocessor or LEDs. When no adapter is attached or
when disabled, the charger draws less than 1µA leakage
current from the battery.
