A TL431 reference IC working alongside the optocoupler to monitor output rail drift. 3. The "UPD" Common Failure Modes and Solutions No I²C

Ensuring fast-acting automotive fuses (Car Mini Fuse) are used in the battery circuit for enhanced safety.

It was deaf and mute. No I²C. No fault reporting. If the 1.8V rail sagged under load, the system would just hang.
