1 / 12 page  LP28601-02 Mar.-2017 Email: marketing@lowpowersemi.com www.lowpowersemi.com Page 1 of 12 Preliminary Datasheet LP28601 3.5A Synchronous Buck Li-ion Charger With Intelligent Path Management，Adapter Adaptive and OTG General Description The LP28601 is a 3.5A Li-Ion battery charger intended for 4.4V~14V wall adapters. It utilizes a high efficiency synchronous buck converter topology to reduce power dissipation during charging. And a synchronous step up function could supply 5V/2A from Li-Ion battery which can be used as the OTG. The LP28601 includes complete charge termination circuitry, automatic recharge and a ±1% 4.2V/4.3V /4.35V float voltage. The LP28601 could manage the power supply for system intelligently. The adapter would satisfy the system`s demand firstly, then charge battery with extra current output capacity from adapter. If the current capacity of adapter could not meet the system demand, the adapter and battery would supply power for system together. When the adapter`s current capacity is low than the set charge current, the LP28601 would decrease the charge current automatically to keep the output of adapter would not be pull down by the chip. Additional features include shorted cell detection; temperature qualified charging and overvoltage protection. The LP28601 is available in a low profile QFN-28 package.
