Functional Features
•
•
•
•
•
•
5 V low-drop voltage regulator
Protected against short to battery voltage, e.g. for off-board sensor supply
Can also be used for CAN supply
VCC2 under voltage monitoring. Please refer to Chapter 15.8 for more information
Can be active in SBC Normal, SBC Stop, and SBC Sleep Mode (not SBC Fail-Safe Mode)
VCC2 switch off after entering SBC Restart Mode. Switch off is latched, LDO must be enabled via SPI after
shutdown.
•
•
Over temperature protection
≥ 470nF ceramic capacitor at output voltage for stability, with ESR < 1ꢀ @ f = 10 kHz, to achieve the voltage
regulator control loop stability based on the safe phase margin (bode diagram).
•
Output current capability up to IVCC2,lim.
