Part Number: LM74800EVM-CD Other Parts Discussed in Thread: LM74800-Q1 Hello
My client wants to know the number of internal transistors and manufacturing year of TI's lm74800 chip, which will be used for FMEDA later. Thanks
Part Number: LM74800EVM-CD Hi team,
Should I disconnect D1 from the EVM to observe over voltage clamp operation shown in "Figure 3-1. LM74800EVM-CD Schematic" in its user's guide?
I found that LM74800EVM-CD can observe over voltage clamping…
Part Number: LM7480-Q1 Other Parts Discussed in Thread: LM74800EVM-CD , , TINA-TI Hi Team,
I am looking for a overvoltage protection clamping circuit at around 17V, and I found the feature mentioned in the LM7480-Q1 datasheet. I happened to have one of…
Part Number: LM7481-Q1 Other Parts Discussed in Thread: LM74800EVM-CD Hi,
Does it have negative voltage at OV pin(or BATT_MON) when Reverse Battery ? I did the test and found there will be a negative voltage at OV pin(or BATT_MON). Can you explain it? We…
You can repeat my experience yourself.
For this you will need: LM74800 Evaluation Module: LM74800EVM-CD www.ti.com/.../slvubu3a.pdf
You will get 100% repeat my problem. The main condition: batteries must be used as a load, as in my diagram (the first post…
Hi Vikas,
As per our analysis a diode (rated for > 100V) in the GND path of the LM7480-Q1 should help withstand -100V at the input. But this solution has not been tested. You can test this solution as per your application on LM74800EVM-CD by replacing…
Hi Iain,
We have verified this condition with our team. We can confirm that in the Ideal diode configuration since the VS pin and C are tied together there should not be any issue in C pin going to -0.8V while input voltage is at 0V.
You can also use LM74800EVM…
HI Finbarr,
Thanks for sharing your results. Below are my comments after reviewing your results.
Even with the tests done with LM74800EVM-CD, you can see that the DGATE is turning OFF at multiple instants. We need to understand why DGATE is turning OFF…
