NIS1050
Protection Interface Circuit
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, five 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 2x2mm WDFN6
surface mount package.
Features
• Lower Power Dissipation and Higher Efficiency vs. Zener Shunt
Regulator
• LDO Highly Stable across Temperature, Operates Without Bypass
Capacitors
• Wide 3-30 V Power Supply Voltage Input Range
• Low−Profile (0.75mm) 6-Lead 2x2mm WDFN6 Package
Typical Applications
• Power Interface for New Generation PMICs from Leading Mobile
Phone and UMPC Chipset Vendors
