Hi Experts,
Good day.
Our customer has the following questions. Please advise.
1. On page 3 SDA has an input arrow, and SCL has an IO arrow, However in the table on page 5, SDA is IO and SCL is input. please advise on this conflict.
2. Is the pin” AC_DET” one function or 2 separate functions? AC function, and another function DET?
3. The same question to #2, for pin 18 “IN_nCC”?
4. Is the thermal pad internally connected with any pin? and for external connection, it must be or should be connected to which pin? please add more details.
5. Is the SDA pin an open drain? also, is there a threshold for it?
6. Are these pins have high impedance PGOOD &PGOOD_BU?
7. Are the following pins below have thresholds?
