When the internal drain comparator detects that the switch current exceeds the preset threshold, the LT1910 immediately turns off the switch and asserts a fault flag.\u003c\/p\u003e\n\u003cp\u003eThe switch remains off for approximately\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e150 ms\u003c\/strong\u003e, as determined by the external timing capacitor\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eC3\u003c\/strong\u003e, and then automatically attempts to restart. If the fault condition persists, the protection cycle repeats until the fault is cleared, thereby safeguarding the MOSFET and the load. Once the switch restarts successfully, the fault flag is reset.\u003c\/p\u003e\n\u003cp\u003eThe LT1910 features a\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e50-mV trip point\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003efor current sensing, which determines the value of the shunt resistor.
