I am using TLE9845 for development, but found that when VS is lower than 4.9V, VDDC will drop to 0V and the chip will not work. But the Datasheet said "Single power supply from 3.0 V to 28 V". So how do I make the chip work at a voltage lower than 4.9V

Hello Freedow
The device is expected to work in the lower Vs range. Can you please describe what you actually have:
- What is the voltage that you measure exactly at Vs?
- Is VDDC dropping to zero and then restarting, i.e. you have a reset?
Best regards
