Other Parts Discussed in Thread: LSF0108
Tool/software:
Hi Team,
I had gone through LSF0204 Translator working
Below points are not very clear to me and I would require a detailed explanation on this
1. How RA1 is not required if the sink current is lesser than 1uA
2. what is the voltage level of A1 at the time and how
I have one more query
Below is my application
We have a single LDO on board 3.3V it will be connected to VREFB and since Target I/O is not always<=VREFB+0.8 we cannot connect that voltage to VREFA directly
In this case, can I use voltage divider from LDO for VREF_A?
I see the LDO should be capable to sink the current (Vref_B - Vref_A - 0.8V) / 200kΩ.
If VREFA LDO doesn't support sinking current I could add a pull_down to VREFA. will it allow me to use single LDO for both VREFA & VREFB?
Awaiting for your reply
Thanks,
Rohini
