Applications Information
(Refer to the
Typical Operating Circuit.
)
Sense Resistor
The circuit-breaker threshold is set to 50mV (typically).
Select a sense resistor that causes a drop equal to or
above the current-limit threshold at a current level above
the maximum normal operating current. Typically, set the
overload current to 1.5 to 2.0 times the nominal load cur-
rent plus the load-capacitance charging current during
startup. Choose the sense resistor power rating to be
greater than (V
