ISL6251AHAZ Controlador de carga da bateria

The ISL6251, ISL6251A is a highly integrated batterycharger controller for Li-Ion/Li-Ion polymer batteries and NiMH batteries. High Efficiency is achieved by asynchronous buck topology and the use of a MOSFET, instead of a diode, for selecting power from the adapter orbattery. The low side MOSFET emulates a diode at light loads to improve the light load efficiency and prevent system bus boosting.
