Tool/software:
Hello team,
VBAT_IN Max is 18V. It cannot connect to battery supply directly considering surge damage.
Could you teach me recommended connection for VBAT_IN in 12V battery vehicle systerm?
Also I want to know quiescent current because I can't find in datasheet.
Regards,
Youhei MIYAOKA
Hi Youhei MIYAOKA,
The datasheet lists typical supply current consumptions for different operating modes, with the top two rows showing shutdown mode (quiescent) current draw.
As for VBAT_IN recommendation, I will close this thread and direct Daveon to the other thread you posted to provide this. He is out of office and will reply sometime this week.
Best,

Hi Garret,
Seems VBATT value is not specified. Can you share VBATT condition for electrical characteristics?

Hi Miyaoka-san,
VBAT_IN is not a device supply voltage, but rather a reference voltage for input fault diagnostics (short to VBAT). Thus, it has no effect on the electrical characteristics of the device. This pin is for monitoring the system battery voltage, not powering the device.
