NEW PRODUCT

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.
