Block Description
Figure 14 Module Block Diagram
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 undervoltage 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.
•
Overtemperature protection
•
≥
470nF ceramic capacitor at output voltage for stability, with ESR < 1
Ω
@ f = 10 kHz, to achieve the voltage
regulator control loop stability based on the safe phase margin (bode diagram).
