onsemi NIS1050
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, five volt supply to the PMIC, and the NFET is the external pass element for the OVIC circuit.| Part No. | NIS1050 |
