LTC4365HDDB-1

The LTC4365HDDB-1 is a robust surge stopper IC designed to protect electronic circuits from overvoltage, undervoltage, and reverse voltage conditions. It operates by controlling an external N-channel MOSFET to disconnect or limit the voltage to the load when unsafe conditions are detected. The device is capable of withstanding input voltages up to 80V and offers precise control over the voltage and current thresholds. Key features include adjustable overvoltage and undervoltage protection, adjustable current limiting, and a fault timer to disable the MOSFET during prolonged faults. The LTC4365HDDB-1 is ideal for automotive and industrial applications where reliable overvoltage protection is critical. It is typically housed in a compact DFN package, making it suitable for space-constrained designs.

The LTC4365HDDB-1 is typically available in a 10-lead DFN (Dual Flat No-Lead) package.

The LTC4365HDDB-1 is a 12-pin device. It is a surge stopper and overvoltage protection controller designed to protect electronic components from overvoltage, overcurrent, and reverse voltage conditions. The device operates by controlling an external N-channel MOSFET to regulate the output voltage during transient voltage events and overcurrent conditions.
Here is a brief description of key pins:
1. VIN: Power supply input.
2. VOUT: Output voltage.
3. GATE: Drives the gate of the external N-channel MOSFET.
4. SENSE+: Positive side of sense resistor for current limiting.
