Note 1: Load dump protection according to ISO7636-2: 2004 pulse 5, Us=+70V
Note 2: Limited functionality when the voltage is higher than the nominal. If the voltage is less than 8,3
V, the control unit is in non-operational state.
Note 3: This parameter is only related to the logic power input.
Note 4: This parameter is influenced by +10V REF’s load level.
Note 5: Nominal voltage level where reverse protection will be activated. Keep in mind the fuse
parameters, such as the reaction time.
