Current Capabilities, Current Limitation and Over Temperature Detection with
Prewarning
• 5V Output Voltage for V1 Regulator
• Three Operational Modes (Normal, Standby and Sleep Mode) Separated
from the CAN Interface Operating Modes
• Low Speed 125kBaud Fault Tolerant CAN Interface, Compatible with
MC33388 Standalone Physical Interface
• V1 Regulator Monitoring and Reset Function
• Three External High Voltage Wake-up Inputs, Associated with V3 V

(1) Version A: If device remains in reset greater than 100ms due
to V1 undervoltage, device switches to sleep mode to minimise
current consumption. Wake-up configuration active.
(2) Version C: In V1 undervoltage condition, device remains in
permanent reset state until V1 returns to nominal conditions. V1
protected by overcurrent and over temperature functions.
(3) Version D: In V1 undervoltage condition, device remains in
permanent reset state until V1 returns to nominal conditions. V1
protected by overcurrent and over temperature functions.
Change of undervoltage reset threshold. Refer to electrical pa-
rameter table, V1 PIn 5V.
