Description

The Over-current limit load switch project presented here provides full protection to devices and loads from access load conditions. The default current limit is set to 1 Amp, however, this load limit is adjustable from 0.4A to 2A with the help of R4 ISET resistor. When an overload condition occurs circuit responds to that overload condition that lasts longer than a fixed blanking period by turning off the load, followed by a retry after the auto-restart time, auto-retry time is 127.5ms. Flag output is pulled up with R1 and the board provides active low output in a fault condition, normally Flag output is high. Power good output is also pulled up and it’s an open-drain output to indicate that the output voltage has reached 90% of the input voltage.Β  The input range of this circuit is 5V to 24V DC. The load can be activated or deactivated with low-voltage logic compatible on Pin4, jumper J1 is provided to activate or deactivate the output. Close the jumper J1 to activate the output load.
