FPF2895C — 28 V/5 A Rated Current Limit Switch with OVP and TRCB
Setting Current Limit
FPF2895C current limit is set with an external resistor
connected between I
SET
and GND. This resistor is
selected using the following equation:



4674.89


/.
(1)
Resistor tolerance of 1% or less is recommended. 5%
tolerance can be achieved only when ILIM is set to larger
than 2A.
