Hi Avishek,
Thanks for confirming. I will add the gate resistor on my next PCB revision.
However, I cannot make this change on my existing PCB. The gate signal is buried on an inner layer. I cannot access the trace to cut it and insert a 10 ohm resistor…
Hi Andy,
Thanks for promoting TI FETs at your customer. The CSD16570Q5B and CSD17570Q5B are the lowest on resistance 25V and 30V FETs in 5x6mm SON package and are optimized for hot swap and OR'ing applications. The next lowest on resistance 25V FET is…
Hello Brett,
This is great - I shared the table and also teh CSD16556Q5B with the customer. I didn't get the max power etc. details however he indicated he was looking to use 2 in parallel. Can I get the SOA curves data tables for botht eh CSD16570Q5B…
Wen,
Our best 25V device for ORing is the CSD16570Q5B. The best 30V for ORing is the CSD17570Q5B.
Both of these devices are significantly lower resistance than the Infineon device, and much higher Qg.
Why is the customer concerned about Qg? Is it…
Salil,
Ok sounds like you can get away with a 25V FET.
I would try the CSD16556Q5B - that should saturate by the 0.9V, especially if the Vgs is not that high on the FET.
It is also excellent in the saturation region
