The FETK-T1.1 implements reverse voltage protection in the same range
and may be used only with central load dump protection.
24 V vehicles require U

disturbing pulse reduction to 12 V vehicle system.
12 V vehicles don’t require special disturbing pulse reductions.
NOTE
The values above are not including the power dissipation of the microcontrol
-
ler ED-RAM part.
NOTE
The FETK-T1.1 will accept permanent power supply voltage dips (for addi
-
tional details of 3 V low voltage operation, see ISO standard 16750).
