Analog Devices Inc. LT4356HMS-1 Surge Stopper

The LT4356HMS-1 from Analog Devices Inc. is a robust surge stopper designed to protect sensitive electronic circuits from high voltage transients and surges. This device is an essential component for systems that are exposed to unpredictable environments where voltage spikes can occur, such as industrial, automotive, and avionics applications. The LT4356HMS-1 ensures that electronic devices operate reliably and are safeguarded against potentially damaging overvoltage events.

Key Features

• Wide Operating Voltage Range: The LT4356HMS-1 can handle a wide range of input voltages, typically from 4V to 80V, making it versatile for various applications.
• Overvoltage Protection: It provides overvoltage protection by controlling the gate of an external N-channel MOSFET to act as a variable resistor during transient conditions, clamping the output voltage to a safe level.
• Adjustable Overvoltage Lockout: Users can set the overvoltage lockout threshold with an external resistor divider, allowing customization for specific circuit requirements.
• Reverse Input Protection: The device is capable of withstanding reverse input voltages, ensuring protection in scenarios where the power supply may be connected backward.
• Low Quiescent Current: It offers a low quiescent current draw, which is particularly beneficial for battery-powered applications where power efficiency is critical.
• Multi-Function Timer: An onboard timer can be used to set fault timeout, ensuring that the MOSFET is turned off after a predetermined period during prolonged overvoltage conditions.
• Robust Packaging: The LT4356HMS-1 comes in a durable MSOP-10 package that is suitable for harsh environments and offers a compact footprint for space-constrained applications.
