The SG6516 provides over-current protection for the
3.3V, 5V, and two 12V rails. Whenever an OCP
condition occurs at any of the voltage rails, PGO is low
and FPO is open. The internal OCP comparators have a
very small offset voltage (±5mV). The sink currents of
IS33, IS5, and IS12 are eight times the current at the RI
pin. The current at the RI pin is V
RI
/R
I
. Below is an
example demonstrating how to set OCP.
If:

OCP active.
To select an R2 resistor:
If
R1=5m
, R

=30K, and
(2)
OCP protection level is 35A, then
(3)
R2 = (I

= (35A
