Hi all,

Is there anyone who has spice model for Si827x and Si823x series gate driver?

I can not understand the calculation in AN901 on page 22 equation 65/65. If i put in the values R5 = 48.1x10^3, n = 3, C = 16uF and Rload = 5V/1A i get an fc of 129kH and not 12kHz. Am I assuming the wrong values? 

I am using the SI3402-B chip to use POE（isolate）.

But it does not work when loading exceed 5V/1.3A.

When I remove the tvs diode of the Transformer primary，it can work at 5V/3A, what is the reason of this phenomenon？

Hello,

 

We have an isolated PoE PD test board with an Si3402-B on board, using a Coilcraft FA2732 transformer to create an isolated +12V at the output.

Class detection works fine, but when starting the PSE, the output ramps to approx. 8V and then it aborts; the PSE reports OVL.

Do you see any obvious issue in the enclosed schematics? Can the opto-coupler have a significant influence on the boot-up process?

 

Thanks for your help.

Hello,

We are testing a DC-DC converter and the gate driver is Si8233BD. A 50kHz, 3.3V PWM is generated from the TI28377S launchpad (DSP) and is given to the driver IC (VIA, VIB). We are getting the VOA output pulses, but the VOB is always clamped to high. Please find the attached schematics. Could you please help us to resolve the issue.

 

Thanks

What is the difference between Si8655BA-B-IU and Si8655BA-C-IU 

If it's in the datasheet , I really can't see it.

Extra credit:  Why is the small-pitch package called a "QSOP?"  I expected pins on four sides.

There is some interference/pulse in IIC line, it is about 1.6V. which may be recognized as high and be outputted in the other side. How to improve this?

For Si8400,  In some systems, there is oscillating at the first logic low. this will cause communication error. After disabling the accelerate function of IIC accelerator, this issue can be solved. See attached "A" waveform. Could you please give some hint to solve this issue according to the existing waveform?
