0V to 16V, Dual Hot-Swap Controller with 10-Bit
Current and Voltage Monitor and 4 LED Drivers
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 compares
before the MAX5970 takes action as determined by the
particular compare and the setting of the PROT input.

The deglitching function is enabled or disabled per com-
parator 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 function for the
corresponding digital comparator.
