AP9050
PROTECTION INTERFACE for PMICs with
INTEGRATED OVP CONTROL
Description
AP9050 is designed to protect the latest generation of PMICs
for portable applications such as UMPCs, smartphones and
others utilizing battery power.
The integrated LDO allows the PMIC to power up and
determine whether the connected power supply (USB or
AC-DC wall adapter) is valid and a safe operation can be
performed.
The PMIC controls the operation of the integrated n-channel
MOSFET to either pass the line voltage or disconnect the line
from the PMIC to protect its internal circuits in the event of an
over-voltage.
The AP9050 is available in a low-profile U-DFN2020-6
package.
