Voltage supervisor circuit using TPS3890-Q1:
My Vin (5 V) is connected to Vmon. R1 and R2 are already defined. Intention is to calculate positive and negative threshold. So I think, this is a kind of reverse engineering.
R1 = 27 K,
R2 = 47 K
From the above read, I calculated as 5 V = Vitp ( 1 + 27/47)
Input Threshold Positive, Vitp = 3.176 V
1) I was not clear threshold calculation from the datasheet. Above calculation is correct or not?
2) What will be threshold negative value, -3.176 V or How to calculate it?
Please comment. Thanks.
