TPS53830A: GSI_n Pin Inquiry

Part Number: TPS53830A

Hi Team.

Could you help to confirm whether we can leave "GSI_n" pin as floating if not used in TPS53830/30A?

it's OD structure, I saw others short it to GND but not sure which way would be the best if we consider current consumption.

Looking forward to your reply.

Thank you.

Hi Evan,

GSI_n can be left floating, however i would recommend tying it to the same pull up source for CAMP (PGOOD) as the GSI_n can be used for debug purposes since there are some faults which will pull GSI_n low. I think this adds 1 additional pull up resistor to the BOM cost.

BR,

Sam G.
