**LTC4368IMS-2#PBF: A High Voltage Surge Stopper for Overvoltage and Overcurrent Protection**

In today's electronics landscape, systems are increasingly exposed to hazardous electrical transients. Voltage spikes, surges, and incorrect power supplies can cause instantaneous and catastrophic damage to sensitive downstream components. Protecting these circuits is paramount for reliability and longevity. The **LTC4368IMS-2#PBF** from Analog Devices is a sophisticated monolithic surge stopper engineered to provide robust **overvoltage (OV) and overcurrent (OC) protection** in a wide range of applications.

This controller operates over an impressive input voltage range, from **4V to 80V**, making it exceptionally suited for automotive, industrial, and aviation systems where large voltage transients are common. Its core function is to regulate the output voltage by controlling an external N-channel MOSFET, acting as a precise series pass element. The device **protects loads by swiftly disconnecting power** when an overvoltage or overcurrent condition is detected, thereby preventing damage.

A key feature of the LTC4368 is its **adjustable overvoltage and undervoltage lockout (UVLO) thresholds**. Engineers can set precise voltage trip points using external resistors, tailoring the protection window to their specific system requirements. Furthermore, it incorporates **accurate current sensing** via an external sense resistor, allowing for precise regulation of the maximum current limit. During a fault, the IC enters a hiccup mode, periodically retrying to re-establish connection. This mode is crucial for limiting power dissipation and preventing thermal runaway in the external MOSFET.

The device is offered in a compact **MSOP-10 package**, enabling its use in space-constrained applications. Its **-40°C to 125°C operating junction temperature** ensures reliable performance even in harsh environments. The LTC4368IMS-2#PBF also features a fast response time, reacting to overvoltage events in mere microseconds to clamp the output before it exceeds safe levels.

**ICGOOFind**: The LTC4368IMS-2#PBF is an indispensable solution for designers seeking robust protection against real-world power anomalies. Its high voltage capability, precise fault management, and flexible configuration options make it a superior choice for safeguarding critical electronics from destructive voltage surges and excessive current.
