TPS3808-Q1: RLRESET/CLRESET Definition

Evan Wang

Part Number: TPS3808-Q1
Other Parts Discussed in Thread: TPS3808,

Hi TI Expert,

Could you help to clarify the definition of the RLRESET/CLRESET in our EC table?

What does it looks like in the diagram/Schematic?

I saw same term in TPS3808E-Q1 datasheet.

Thank you.

Hi Evan,

Thanks for your question.

RLreset is the pull up resistor at the Reset pin, and CLreset is defined for the parasitic capacitor behavior seen on the PCB board.

Hi Slia,

Then I assume the CLRESET is the value we got from the TPS3808EVM since the testing result should come from that.

Am I right?

Hi Evan,

If you look at the datasheet, the capacitor CLreset and pull up resistor RLreset is connected to Reset pin.

Best,

HI Evan,

And I also want to clarify that CLreset capacitor is representing the parasitic capacitor and it's hard to tell the exact value on the PCB board.

Thanks,

Hi Sila,

Got it.

Since the datasheet of TPS3808-Q1 didn't mentioned about it.

The one you showed come from TPS3808 datasheet.

Thank you.
