LP28300AQVF Overview

With CP, OTP 18V withstand voltage 2A switching charging

Preliminary Datasheet
LP28300
2A Synchronous Buck Li-ion Charger
General Description
The LP28300 is a 2A Li-Ion battery charger. It utilizes
a 500KHz synchronous buck converter topology to
reduce power dissipation during charging. Low power
dissipation, an internal MOSFET allow a physically
small charger that can be embedded in a wide range
of handheld applications. The LP28300 includes
complete charge termination circuitry, automatic
recharge.
Battery

timeout
and
end-of-charge indication parameters are set with
external components. Additional features include
shorted cell detection; temperature qualified charging
and overvoltage protection. The LP28300 is available
in a low profile ESOP8/TDFN-10 3*3mm and package.
