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

NEW PRODUCT
operates as a switch and passes the input voltage through to the
output till the input reaches a clamp voltage limit. Once VIN goes
2
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 a low-profile
W-DFN1114-3 package with a typical height of 0.8mm.

Application Information
Over-Voltage Protection
AP9060 protects sensitive circuits by clamping the input voltage to a safe level. In other words, AP9060 conditions the input voltage before
presenting it to the sensitive circuitry.
The clamp voltage on AP9060 is set to 11.15V (typically at room temperature). Therefore, the sensitive circuitry will not be exposed to a voltage
greater than 11.15V. As a consequence, it is important to ensure that the sensitive ICs that follow AP9060 are safe to operate up to the clamp
NEW PRODUCT
voltage level (refer to Figure 4 for variation in clamp voltage over temperature).
If the input voltage is below VCLAMP, the PMOS pass transistor in the AP9060 fully turns on and only I x RON is dropped across the FET (where, I
is the current drawn by the sensitive ICs). On the other hand, if VIN is greater than the clamp voltage, then AP9060 limits the drive to the FET to
ensure that the voltage on VOUT is maintained at the clamp level.
Over-Temperature Protection
As a secondary protection mechanism, AP9060 incorporates an over-temperature shutdown feature. Therefore, if the sensitive circuitry draws
too much current either in normal mode or in the clamp mode, AP9060 will turn off the PMOS transistor, provided the junction temperature
exceeds the thermal shutdown threshold (THMSD). Thereafter, the device will resume normal operation once the junction temperature falls below
THMSD – THMhyst.
In the clamp mode, given that any input voltage above VCLAMP is dropped across the pass transistor in AP9060, care must be taken to keep the
power dissipation within AP9060 in check by minimising the current drawn in this mode.
Fast Input Transient Protection
AP9060 will also protect the sensitive circuits against fast input transients. Upon detecting a fast transient on VIN, AP9060 reduces the drive to
the FET in order to minimise the overshoot on VOUT. With 100nF on VOUT, if the voltage on VIN goes from 0V to 30V in 100ns, the output
voltage will not peak above Vpk.
Reverse Operation
AP9060 supports the USB OTG specification and can operate in the reverse direction as well. Therefore, if the sensitive circuitry drives a voltage
on VOUT (VOUT_REV) and a load is connected on VIN (IIN_REV), then AP9060 will turn the FET on in the reverse direction and only I x RON will be
dropped across the device, similar to the forward operation.
However, note that neither over-voltage nor over-temperature protection mechanisms will function in this mode.
Output Capacitor
It is recommended to have a capacitor on VOUT in a range between 100nF and 10µF.
Output Resistor
It is recommended to have a resistor on VOUT in a range between 10kΩ and 100kΩ. AP9060
