2 Cell / 3 Cell Narrow VDC Charger with SMBus Interface - BD99950MUVThe 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. With a small inductor, PWM switching frequency can also be programmed by SMBus up to 1.2MHz.
