regrading the part UP1966E I want confirmation that it is the same as UP1966A as it mentioned in other names
Hello aiprogroup and welcome to the DigiKey TechForum.
Generally, when we have another name listed on the product page, it is an indication that the manufacturer changed the part number or have it listed as another name. I wasn’t able to confirm this with documentation, as I do not see that EPC has specifications or documentation for uP1966A. The only mention I see of this would be in regard to eval boards. It does seem that the uP1966A may be an older gate driver.
