• Easy Integration: Can be easily integrated into existing circuit designs due to its simple pin configuration.

Disadvantages

• External MOSFET Required: The LTC4360CSC8-1 requires an external N-channel MOSFET for operation, adding complexity to the circuit design.
• Limited Operating Temperature Range: The IC has an operating temperature range of -40°C to 85°C, which may not be suitable for extreme environments.

Working Principles

The LTC4360CSC8-1 operates by continuously monitoring the input voltage. When the voltage exceeds the set overvoltage threshold, the IC turns off the external MOSFET, disconnecting the load from the input source. In the case of reverse voltage, the IC detects the condition and prevents current flow in the reverse direction. The adjustable thresholds allow users to tailor the protection levels based on their specific requirements.
