Hello;
I'm unclear about the explanation and actual operation of the the 76920's AOLD (and ASCD) protections, vs. that of the explanation in the 78350 TRM.
As per 10.3.1.2.1 in the 920 datasheet, the programmable delay for the HW protection OCD (= 78350's AOLD) is limited to 8 discrete periods, from 8ms to 1280ms:
But the 78350 TRM lists a range of delays and counters that far exceed those of the 920?
I don't understand how the 78350 can implement these delays. But I want to delay opening the discharge fet for 30 seconds during an AOLD event...But unless I'm misunderstanding, it seems that the 920 will disable the fet in no later than 1280ms?? Does this mean that it actually would in this case, but that the 78350 immediately turns it back on?
Protections AOLD Threshold and Delay H1 0x00 0xFF 0x00 <- this appears to correspond to the 920's PROTECT2 register
