BD99950MUV Description
The BD99950MUV is a high-efficiency, synchronous Narrow VDC system voltage regulator and battery charger controller. It has two charge pumps which separately drive N-channel MOSFETs for automatic system power source selection. Charge voltage, charge current, AC adapter current and minimum system voltage can be programmed through SMBus.
