Variable Over-Current Detection Load Switch

This over-current latch load switch provides over-current protection, thermal shutdown protection, soft-start function, and low power OFF function. The Overcurrent protection function is activated when the load is shorted. This protection function is effective in preventing damage due to sudden and unexpected incidents. It is also equipped with an error flag notification pin which indicates thermal shutdown and over-current condition. The project can help to protect the connected device from overcurrent, monitoring of various power lines, and power management. The board operates from 12V DC to 24V DC. The power LED indicates the output. Screw terminals provided for an easy connection of input and output supply. For the Fault function, additional 5V VCC DC input is required, otherwise, the VCC is not required. The circuit is normally enabled, and you can connect enable pin to GND to disable the output. Output is latching type; power is OFF when a fault condition occurs and sequence can be reversed with power OFF or Disable/Enable Pin.
