The LT4363CMS-2#TRPBF from Analog Devices is an overvoltage protection regulator designed to protect load circuitry from high voltage surges and transients, particularly in automotive applications. It operates from a wide supply voltage range of 4V to 80V and can withstand negative voltages down to -60V without damage.
This device drives an external N-channel MOSFET as a pass transistor, offering low power loss due to its internal charge pump. It features an active current limit circuit that monitors voltage across an optional sense resistor, regulating the output to protect the MOSFET. The fault timer allows the load to continue functioning during short transient events, with the timer period varying based on the voltage across the MOSFET.
The LT4363CMS-2#TRPBF is supplied in a 10-MSOP package and is suitable for applications requiring robust protection against voltage spikes and overcurrent conditions. Its design supports high availability systems that must continue operating during transient events.
Key electrical characteristics include a wide operating voltage range and precise current limiting thresholds. The device also supports a reset function via the SHDN pin, requiring a specific low pulse duration and a controlled slew rate for high-level transition.

The LT4363CMS-2#TRPBF operates from a supply voltage range of 4V to 80V.
The device can be pulled below ground potential by up to 60V without damage.
An active current limit circuit controls the GATE pin to limit the sense voltage to 50mV when the OUT pin potential is above 2V, and to 25mV for severe output shorts.
The fault timer allows the load to continue functioning during short transient events while protecting the MOSFET from damage due to prolonged supply overvoltage.
To reset the part, the SHDN pin must be pulled low for at least 100µs, then pulled high with a slew rate of at least 10V/ms.
