The LTC4359 Datasheet explains how the device functions as an ideal diode, mimicking the behavior of a Schottky diode but with significantly reduced forward voltage drop. This is achieved by controlling an external N-channel MOSFET. The LTC4359 turns on the MOSFET when the input voltage is higher than the output voltage, allowing current to flow. Conversely, it turns off the MOSFET when the input voltage is lower, preventing reverse current flow. Key applications highlighted in the datasheet include:
- Reverse Supply Protection: Prevents damage from accidental reverse polarity connections.
- Load Sharing: Enables multiple power supplies to share the load equally.
- OR-ing Power Supplies: Allows seamless switching between redundant power supplies.
Furthermore, the LTC4359 Datasheet offers detailed guidance on selecting appropriate external components, such as the MOSFET and sense resistor. It explains how to calculate the power dissipation in the MOSFET and how to choose a suitable heat sink, if required. A small example illustrates this point:
| Parameter | Value |
|---|---|
| Input Voltage | 12V |
| Maximum Current | 5A |
By carefully considering these factors, designers can ensure the reliable and efficient operation of their circuits.
