Description

AP9060 is designed to protect the latest generation of PMICs for portable applications such as Smartphones, UMPCs and others that utilize battery power.

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 V above the clamp limit, which is set to 11.15V, the output voltage gets clamped and the feedback loop maintains the clamped V 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.

NEW PRODUCT

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 u p to the clamp voltage level (refer to Figure 4 for variation in clamp voltage over temperature).

If the input voltage is below V is the current drawn by the sensitive ICs). On the other hand, if V ensure that the voltage on VOUT is maintained at the clamp level.

, the PMOS pass transistor in the AP9060 fully turns on and only I x R

IN

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 (THM

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 V

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 (V dropped across the device, similar to the forward operation.
