LINE A PROTECTION :
– For positive surges versus GND, the diode D1
will conduct.
– For negative surges versus GND, the protection
device P1 will trigger at a voltage fixed by the
-VBAT reference.
LINE B PROTECTION :
– For surges on line B, the operating mode is the
same, D2 or P2 is activated.
It is recommended to add a capacitor (C=220nF)
close to the gate of the LCP, in order to speed up
the triggering.
ct(s) Surge peak current versus overload duration.
