Part Number: TPS2412 Hello,
I'm quite disapointed regarding the application note SLUA486 titled "High-Voltage ORing with Low-Voltage Controllers"
The schematic in this document use Si3442 Mosfet for Q5 and Q6, it is a 20V/5A mosfet.
Suppose PS1…
Part Number: TPS2412 Other Parts Discussed in Thread: TPS2410 Hello,
I have two standard circuits (I think) per the datasheet for this TPS2412 in parallel. Both are supposed to pass 5V to the PCB. One 5V circuit passes USB 5V. The other passes a power…
Hello again,
This is still of importance.
They can differ as much as allowed. What we are interested in currently is being presented/suggested different solutions. Would be great if you can assume the differ by 1V in one case and by e.g. 50 or 100mV…
Part Number: TPS2412 Other Parts Discussed in Thread: MSP430FR5969 Hello,
My schematic is attached.
Questions 1:
Per section 8.3.6 TI recommends that a fet with 1nF Ciss or greater is used. I'm referring to the first of the three bullet points.…
Other Parts Discussed in Thread: TPS2412 Hi to all,
Could someone tell me what frequency works the internal charge pump of the TPS2412 ?
I have some trouble during EMC qualification and I suppose is the the TPS2412, but I don't find the frequency…
Part Number: TPS2412 All,
I have a question about TPS2412 Vdd pin. Pin C (pin 6) connects a 12V always existing. Vdd (pin 1) ties same 12V source with a switch to turn ON/ Off.
if Vdd pin is turn off (no 12V source), is there leakage current from…

There can be substantial leakage from C-A on the TPS2412. See attached measurements and simplified model based on different potential voltages.
The LM74670 can have over 100uA leakage per the DS ES table.

Part Number: TPS2412 Hello,
I've been reading old forum posts to better understand this part. I've run across this one that touches on a concern I have.
Question1
It sounds like there is a fair amount of leakage current with these parts and…
Other Parts Discussed in Thread: TPS2412
Our customer found that there is some residue voltage on Oring controller TPS2412 pin A. VDD is powered from 12V bus. The test condition is two PSUs in parallel and only peer PSU has 12V on the bus, the local…
