Hi,
I apologize that no one has followed up with your question. I'm going to close this thread, but if you still have a question please feel free to post a brand new thread instead of replying to this one. We will do our very best to respond within…
Other Parts Discussed in Thread: LM25066IA , LM25066 , LM25066I Hello,
I'm trying to prevent an over current fault condition from switching off the MOSFET using a LM25066IA. I understand the risk of doing this in my design, but I have other protection in…
Hi Spencer,
My apologies we did not catch this earlier.
When we do this in the lab, we tend to apply 4V on Vdd, while Vin is unplugged. Then we hot plug Vin. But if Vin is already connected and off (discharge/capacitance bank), then yes it seems it…

Hi Mike,
Thanks for reaching out to us.
The key difference among LM25066I, LM25066A, LM25066IA, and LM25066 is telemetry accuracy. Please refer to the “Telemetry Accuracy” of “Electrical Characteristics” table in each datasheet for more details.…
Hi Kazuki,
All the variants of LM25066 are pin to pin compatible and same from the hardware point of view. The key difference among LM25066I, LM25066A, LM25066IA, and LM25066 is telemetry accuracy. Please refer to the “Telemetry Accuracy” of the “Electrical…
Part Number: LM25066I Other Parts Discussed in Thread: , LM25066 Hi all,
Is it possible to get the offset value for LM25066I & LM25066IA respectively? Thanks.
Hi Chang,
We have Telemetry Current Sense Accuracy data for LM25066I at 25mV in Datasheet as shown below,
The Accuracy will worsen for 1mV as it will be close to the offset voltage of the Amplifier.
If you want a better accurate part, consider using…
Hi Chris,
From your report it is evident that with increase in Current, the measurement accuracy increases and vice-versa. The reason is as mentioned in the datasheet is primarily due to offset voltage of internal amplifier and external noise. So, we…
