Over voltage and programmable OVP
Once VCC crosses the turn-ON threshold and the device is enabled (OUTEN = 1), L6713A
provides an Over Voltage Protection: when the voltage sensed by VSEN overcomes the
OVP threshold, the controller permanently switches on all the low-side MOSFETs and
switches OFF all the high-side MOSFETs in order to protect the load. The OSC/ FAULT pin
is driven high (5V) and power supply or OUTEN pin cycling is required to restart
operations.The OVP Threshold varies according to the operative mode selected (See
Table 11).
The OVP threshold can be also programmed through the OVP pin: leaving the pin floating, it
is internally pulled-up and the OVP threshold is set according to Table 11. Connecting the
OVP pin to SGND through a resistor ROVP, the OVP threshold becomes the voltage present
at the pin. Since the OVP pin sources a constant IOVP=12.5A current(See Table 4), the
programmed voltage becomes:
Filter OVP pin with 100pF(max) vs. SGND.

PGOOD (only for AMD mode)
It is an open-drain signal set free after the soft-start sequence has finished. It is pulled low
when the output voltage drops below -300mV of the programmed voltage.
