Hi Vladimir,
I think the major cause here is an improper layout. Keep in mind that when a short circuit occurs dozens of Ampères will flow through R9 and all involved "230V N" connections:
So all the different "230V N" nodes in your schematic can…
Hi Stanley,
Please reference pages 8 and 9 on the tech note that I have attached for more information on ESD diode clamping. Additionally, you will not need to worry about phase inversion.

Hi Charles,
I assume the spec you're more interested in is Input Bias Current and how your resistor divider on the front end could impact the accuracy of the comparator. Input Resistance is generally an older term used for our older parts.
It's important…

hi,
Attached is the datasheet I’m using, I couldn’t find any information in it regarding what to do with unused input pins. I’m hooking the positive supply to 15V and the negative supply to ground.

Dear Sir, please answer
There is feature description from LM2901 datasheet, page 10: "The output NPN sinks current when the positive input voltage is higher than…
Hello Todd,
Are you are referring to the National Semi version (-N), or the TI version?
I will respond for the National version..
No. The LM2901 (or LM139/239/339/3302) does NOT have ESD diodes on the inputs.
This is why it only has a 600V…
Other Parts Discussed in Thread: LM339 We had downloaded a pSpice model of LM339 from TI.com ! We then simulated an LM339 based square wave oscillator circuit on TINAPro Version 7 Circuit Simulation Software by DesignSoft Inc.! But the circuit doesn't…
Part Number: UCC28063A Hi Sir,
My customer plan UCC28063A design 600W SMPS. Currently has MOSFET damage when start up PFC. I think is noise interfere control card(UCC28063A), since we use wrap up inductor with copper and wire to GND. improve MOSFET…
