I've been running this roadtest for about 2 weeks: Infineon Gate Driver with Truly Differential Inputs: Infineon Gate Driver with Truly Differential Input

Right now, I have 3 applicants, with 10 kits given to me for the RoadTest.

I'm trying to determine why there hasn't been more interest. Is it the messaging on the landing page that's confusing? Not interesting? You're too busy? Too complicated? No Test Equipment?

I'll agree this is not your typical maker dev board. The product being evaluated would be in a gate driver IC -- part of a larger design such as DC-DC converter, an inverter, or other power supply. It would be ideal for someone into power supply engineering.

A little bit about the gate driver IC: It's a new family of single-channel non-isolated gate-driver ICs from Infineon. Due to the unique fully differential input circuitry with excellent common-mode rejection, the logic driver state is exclusively controlled by the voltage difference between the two inputs, completely independent of the driver’s reference (ground) potential. This eliminates the risk for wrong triggering and thus is a significant benefit in all applications exhibiting voltage differences between driver and controller ground, a problem typical for systems with 4-pin packages (Kelvin Source connection), high parasitic PCB inductances (long distances, single-layer PCB) or a bipolar gate drive. https://www.infineon.com/dgdl/Infineon-1EDN8550B-DS-v02_00-EN.pdf?fileId=5546d46262b31d2e01635da0c1c02652

So, could you take my poll and give me an idea why this roadtest is not enticing you to apply?

Thanks.
