For this PCN, the wafer process cha

For this PCN, the wafer process change from 6" to 8" cannot be changed back. There was no change to the HSP10 fault circuit, only more of them printed on a larger wafer. The change did not result in a footprint change for the A3942. The change also did not involve any datasheet changes to the allowed ranges of diagnostic current (48uA to 82uA at 1.35V) or trip point voltage (1.4V to 1.6V). Testing performed with IC's from the 8" wafers did not show a difference in the diagnostic performance when used with a proper load. But We really see litter difference when use with improper load, which is out of Tir2 supplier's control. we also will try to contact with Tir2 supplier to see does there any possibility to change this PCN back.
