It is optimal for detecting overcurrent between the load device and GND, preventing degradation or destruction of ICs and components from overcurrent due to load short circuits, etc.!
This product monitors overcurrent by inserting a current detection resistor between the load device and GND, and it outputs a signal (High signal) to indicate an abnormal condition when overcurrent is detected. It has a built-in timer circuit, allowing the detection time to be set using an external resistor and capacitor for the time constant. The product includes an RS latch circuit, which continues to output an abnormality signal regardless of the presence of overcurrent after detecting overcurrent beyond the timer duration. To reset the latch, it is necessary to either reapply power or input a reset signal to the product, ensuring safe resumption of operation. As it is a low-side overcurrent detection type, the IC can operate with a separate power supply from the load. Therefore, it is also capable of detecting overcurrent for loads powered by high-voltage supplies.
