The LP4020 is a 2A Li-ion battery charger. It utilizes a 600KHz synchronous buck converter topology to reduce power dissipation during charging. Low power dissipation and internal MOSFET allow a physically small charger that can be embedded in a wide range
of handheld applications. The LP4020 includes complete charge termination circuitry, automatic recharge and ±1% 4.2V float voltage.
Additional features include shorted cell detection; temperature qualified charging and overvoltage protection. The LP4020 is available in a low profile SOT23-6/ESOP8 package.
