Intersil ISL6252
The ISL6252, ISL6252A is a highly integrated battery charger controller for Li-ion/Li-ion polymer batteries. The low side MOSFET emulates a diode at light loads to improve the light load efficiency and prevent system bus boosting. The constant output voltage can be selected for 2, 3 and 4 series Li-ion cells with 0.5% accuracy over-temperature.| Part No. | ISL6252 |
