There's a on-going need for that type of driver all in one package. I'm still surprised that the original was discontinued. But then the IPS6041 high side relay driver with short/open circuit detect was also discontinued and I ended up doing a change on 4 different PC boards to handle a different dual channel device. And I didn't make those changes until I had 500 of the items in stock.

Expensive even if the time to do it is free. And this chip shortage isn't only with processors. I use 3 of the ones shown in the attached photo on each product. The mouser delivery date keeps changing between where it is now and June 2023. And they were ordered last year at this time (2021). John > > > > On 16.
