Tell us about the LTC2977.
Please tell me the min value of 「Diffrential Input Current」 described on page 6 of the data sheet.
The typical value is described as 10uA.
Since we do not have a minimum value in the datasheet, I had to get the data from our test engineering group. It appears that the minimum value we have seen is 4uA. The differential current is defined as the Vsensep current minus the Vsensem current. That is, the Vsensep current > Vsensem current. May I ask why you need to know the min value?
Thank you for your quick response.
Because my customer divides the input voltage and inputs it to Vsense,
it is affegted by the high resistance value used there.
I am asking the customer to lower the resistance value that has no influence,
However, I was asked to them confirm the device's current minimum.
The reason for viewing the input voltage with Vsense we want to use the PWRGD function as well.
My perception is that the PWRGD function can not be used for Vinsns of the LTC2977.
Is there a difference?
