Working Principles

The LTC4412HS6#TRMPBF utilizes MOSFET technology to control the flow of current. It compares the input voltage with the reference voltage and controls the gate voltage of the internal MOSFET accordingly. When the input voltage is within the specified range, the MOSFET remains on, allowing current to flow through. If the input voltage exceeds the overvoltage threshold or falls below the undervoltage lockout level, the MOSFET turns off, disconnecting the load.

Application Field Plans

The LTC4412HS6#TRMPBF can be used in various power management applications, including:

1. Battery-powered devices
2. Portable electronics
3. Automotive systems
4. Industrial equipment
5. Power supply units
