Part Number: TLV3691
My customer want to know following two point to estimate battery life. Could you answer the questions below.
1. What is the current consumption during H and L output? do you think additional current leakage will be added, or it will be same as Iq spec indicated in the datasheet, 200nA?
2. What is the maximum current consumption during device operation? And when is the maximum timing?
In regards to quiescent current, the dominating factors are temperature and process variation. So output high or low is not a significant contributing factor when considering the max value. The 200nA spec in the datasheet will cover both output conditions.
I do not believe that I understand question 2. The quiescent current specified in the datasheet is measured with a static input condition.
In regards to max timing, are you referring to propagation delay? If so, you can anticipate that the prop delay can vary as much as +/- 30% over temperature and process from the typical values for a specified overdrive voltage. Our datasheet specifies prop delay with a 100mV overdrive. We also provide plots for prop delay versus input overdrive in figures 7 and 8. These curves will have a +/-30 window around them as mentioned previously.
If for reason your customer needs faster response and can accept higher quiescent current, the TLV7031 is a good alternative.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
