Deglitching of Digital Comparators
The five digital comparators per hot-swap channel
(undervoltage/overvoltage warning and critical, over-
current warning) all have a user-selectable deglitching
feature that requires two consecutive positive com-
pares before the MAX5961 takes action as determined
by the particular compare and the setting of the PROT
input.
The deglitching function is enabled or disabled per
comparator by registers dgl_i, dgl_uv, and dgl_ov
(Tables 38, 39, and 40). Writing a 1 to the appropriate
bit location in these registers enables the deglitch func-
tion for the corresponding digital comparator.
