Over voltage and programmable OVP
Once VCC crosses the turn-ON threshold and the device is enabled (OUTEN = 1), L6714
provides an Over Voltage Protection: when the voltage sensed by VSEN overcomes the
OVP threshold, the controller permanently switches on all the low-side MOSFET and
switches off all the high-side MOSFET 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 10
).
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 10
. Connecting the
OVP pin to SGND through a resistor R
OVP
, the OVP threshold becomes the voltage present
at the pin. Since the OVP pin sources a constant I
OVP
= 12.5
μ
A current(
See Table 10
), the
programmed voltage becomes:
Filter OVP pin with 100pF(max) vs. SGND.
16.4
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.
