TLIN1431-Q1: pullup on PIN/nCS needs to be 500k? or 10k?

Jonathan Jank

Part Number: TLIN1431-Q1

Tool/software:

customer is using TLIN14315-Q1 and wants to configure I/O as 5V. Datasheet says use 500kohm pullup to 5V on PIN/nCS pin to do this. The customer wants to use 10k pullup instead.

Can we do this? what are the bounds on the 500k pullup that will work for this ? will 10k work ?

thanks,

Hi Jonathan,

Thanks for your patience. The 500K Ohms pull-up here is only for limiting current. 10K Ohms will still work they will just see a higher current when using stronger pull-up.

Sean
