GENERAL DESCRIPTION
The LP28501 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 LP28501 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 LP28501 is available in a low profile QFN-28 package.
