Require No Sense Resistor
16 ______________________________________________________________________________________
To determine the proper circuit-breaker resistor value
use the following equation, which refers to Figure 12:
where I
TRIPSLOW
is the desired slow-comparator trip
current.
The fast-comparator trip current is determined by the
selected R
CB
value and cannot be adjusted indepen-
dently. The fast-comparator trip current is given by:
SC_DET must be connected to OUT through the select-
ed R

SENSE
.

Mode
When operating with R
SENSE
, calculate the circuit-
breaker threshold using the worst possible operating
conditions, and add a 20% overcurrent margin to the
maximum circuit current. For example, with a maximum
expected current of 2A, using a 20% margin, the cur-
rent for calculation is (2A) x (1.2) = 2.4A. The resulting
minimum circuit-breaker threshold is then a product of
this current and R
SENSE
= 0.06&, or (0.06&) x (2.4A) =
0.144V. Using this method to choose a false circuit-
breaker threshold allows the circuit to operate under
worst-case conditions without causing a circuit-breaker
fault, but the circuit-breaker function will still detect a
short-circuit or a gross overcurrent condition.
To determine the proper circuit-breaker resistor value,
use the following equation, which refers to Figure 13:
where, I
TRIPSLOW
is the desired slow-comparator trip
current.
The fast-comparator trip current is determined by the
selected R
CB
value and cannot be adjusted indepen-
dently. The fast-comparator trip current is given by:
