TMCS1123: UL certification

Part Number: TMCS1123

We are looking for a component for current measurement for a new project. I evaluated the TMCS1101A1B. Now a colleague has found out that the isolation voltage specified in the data sheet of 4242VPeak / 3,000VRMS refers to basic insulation or a voltage transient. The colleague then immediately found the “solution” to the problem in a forum; the TMCS1123 series promises to no longer have this problem and offers double insulation. The TMCS1123 series apparently still has UL approval (“pending”). Unfortunately, we absolutely need this approval.

Can you comment what the current status is at UL? I hope to hear from you soon.
