Part Number: TPS3808

Hi team,

I want to use TPS3808G18 for Reset delay, and I don't care the supervisory function. And for VDD, I have both 1V8 or 3V3;

According for the Vit of TPS3808G18 is 1V67, if use 1V8 as VDD, there will be a certain risk of triggering low voltage protection. So I want to use 3V3 as VDD power for SENSE and VDD pin of TPS3808G18;

Could I configure like this?

Best regards,

Andy Liu

Hi Andy,

I just want to clarify with you, you want to use the TPS3808G18 with the 3.3V rail? If that is the case, then you should be ok.
