AP9060
OVERVOLTAGE CLAMP
Description
Pin Assignments
AP9060 is designed to protect the latest generation of PMICs for
portable applications such as Smartphones, UMPCs and others that
utilize battery power.
W-DFN1114-3

The device, with its integrated low resistance p-channel MOSFET,
operates as a switch and passes the input voltage through to the
output till the input reaches a clamp voltage limit. Once VIN goes
above the clamp limit, which is set to 11.15V, the output voltage gets
clamped and the feedback loop maintains the clamped VOUT by
reducing the drive to the p-channel FET.

The output voltage is clamped at 11.15V to ensure that a following
PMIC can detect a faulty charger and ensure safe and proper
communication to the system.
AP9060 also supports reverse operation whereby it can pass up to
1A of current from the PMIC to the load connected to the USB port.
This makes AP9060 suitable for USB On-The-Go enabled devices.
The AP9060 protection device is available in
W-DFN1114-3 package with a typical height of 0.8mm.
