TPS25750: PP5V and VIN_3V3 in Dead Battery mode

Kei Kuwahara

Part Number: TPS25750

Hello team,

The customer is using the TPS25750D with just sink mode 12V/2A in PPHV. This is thier main power supply.

Customer application doesnt have any battery, so the customer is using the device with dead battery mode all the time.

Question:

Is it okay to leave the PP5V and VIN_3V3 floating in this case?

Best Regards,

Hi Kei,

This is our recommendation for sink only for 25750.

In the thread, we recommend grounding PP5V and connecting the VIN_3V3 pin to ground through a 10uF cap.

Thanks and Regards,

Chris
