Protection Interface for PMICs with Integrated OVP Control

The NIS1050 is a protection IC targeted at the latest generation of PMICs from the leading mobile phone and UMPC chipset vendors. It includes a highly stable low current LDO and a low impedance power N-Channel MOSFET. The LDO provides a low current, 5.0 volt supply to the PMIC, and the NFET is the external pass element for the OVIC circuit. These stages combine with the internal PMIC to protect the charging circuit from low impedance overvoltage conditions that can occur from either the ac-dc or USB supply. The NIS1050 is available in the low profile 6-lead 2 x 2 mm WDFN6 surface mount package.
