Part Number: TLIN1021A-Q1

Hello team,

TLIN1021A-Q1 datasheet say unused WAKE pin should be tied up to VSUP or GND.

Are pull-up(or pull-down) resistor necessary or just simply pull it w/o resistor?

If needed, please guide me resistance.

Thank you.

Hi Oliver,

You can short the WAKE pin to VSUP or GND. Shorting it to VSUP will actually consume less current than shorting it to GND since the WAKE pin is internally biased to VSUP.

Best,

Chris
