Overview of LTC4361IDC-2 from Analog Devices Inc.

The LTC4361IDC-2 is a robust overvoltage and overcurrent protection device designed by Analog Devices Inc. to safeguard sensitive electronic components. This advanced circuitry is engineered to protect low voltage systems from transient voltages and current surges that can occur due to a variety of reasons such as power supply malfunctions, lightning strikes, or load dump in automotive environments.

Key Features

• Overvoltage Protection: The LTC4361IDC-2 offers precise overvoltage protection by controlling an external N-channel MOSFET to disconnect the load when the input voltage exceeds the set threshold.
• Overcurrent Protection: Alongside overvoltage protection, it also provides overcurrent protection by monitoring the voltage across a sense resistor and turning off the MOSFET when the current exceeds the user-defined limit.
• Wide Operating Range: It operates over a wide voltage range, typically from 2.5V to 5.5V, making it suitable for a variety of low voltage applications.
• Adjustable Turn-On and Turn-Off Thresholds: Users can set the overvoltage turn-off threshold and the undervoltage turn-on threshold to ensure precise control over the protection parameters.
• Fast Response Time: The device reacts quickly to fault conditions, providing a fast response time that is critical for preventing damage to sensitive components.
• Low Quiescent Current: It features a low quiescent current, which minimizes power consumption when the device is in standby mode.
