OCP Point Limited: 110%-130% auto restart OCP 110% - 130%

The output will be blocked when output is over-current, and should automatically recover when fault condition is removed 5.3. FOD function /FOD 5.3.1 The FOD full name Foreign Body Detection. The FOD function test of the Qi wireless charging TX terminal must be use the dedicated receiver TPR#5 and four standard foreign objects (FO#1, FO#2, FO#3, FO#4) in the WPC specification. During FOD function test of Qi wireless charging TX device, its output power is adjusted according to the power tolerance packet of TPR#5 to make the TX transmitted power equal to the required power of TPR#5 (1%

tolerance allowed) , so as to ensure that the receiver device will not be damaged due to excessive power. When there are foreign body FO#1/2/3/4 between the working interface of TX device and TPR#5, the output power of TX device will increase due to the absorption of electromagnetic wave by foreign body. When the embedded software system of TX device detects that the output power is over the threshold value set by TPR#5, it is judged that foreign body exists between the working interface of TX/RX, and then stop the power output and flash red light for warning. When the FOD protection is triggered, because of the TX device has stopped power output, power detection cannot be performed again. Therefore, remove the foreign body FO#1/2/3/4 from the working interface of TX/RX, TX device will not return to normal operation, and TPR#5 needs to be replaced. Shenzhen JFH Technology Co.,Ltd WPC specification requires that when FO #1/2/4 are between the TX device and the TPR#5 working interface, TX stops working or FO temperature is lower than 60 is qualified. When FO#3 is between the TX device and the TPR#5 interface, TX stops working or FO temperature is lower than 80 is qualified. JFH-PWC-TX332_SPEC In theory, any Qi certified RX device (such as a mobile phone) can replace the TRP#5 and FO#1 /2/3/4. But the RX device manufacturer has component tolerance in mass production, so it cannot be ensured that the TX device will detect FO#1/2/3/4 between the phone and the TX interface.
