Feedback disconnection
L6716 allows to protect the load from dangerous overvoltage also in case of feedback
disconnection. The device is able to recognize both FB pin and FBG pin disconnections, as
shown in the Figure 26.
When VSEN pin is more than 500 mV higher then VPROG, the device recognize a FBG
disconnections. Viceversa, when CS1- is more than 700 mV higher then VSEN, the device
recognize a FB disconnection.
In both of the previous condition the device stops switching with all the MOSFETs
permanently OFF and drives high the OSC/FAULT pin. The condition is latched until VCC or
OUTEN cycled.
