The three ICUT_ bits (Tables 34a and 34b) allow pro-
gramming of the current-limit and overcurrent thresholds
in excess of the IEEE 802.3af standard limit. The
MAX5952 can automatically set the ICUT register or can
be manually written to by the software (see Table 3).
Class 1 and 2 limits can also be programmed by soft-
ware independently from the classification status. See
Table 3. A reset or power-up sets R2Ah = R2Bh = 00h.
The IVEE bits enable the current-limit scaling (Table
32). This feature is used to reduce the current limit for
systems running at higher voltage to maintain the
desired output power. Table 33 sets the current-limit
scaling register. A reset or power-up sets R29h = 00h.
