LTC4357HDCB#TRMPBF Product Details
The LTC4357HDCB#TRMPBF is a positive high voltage ideal diode controller that drives an external N-channel MOSFET to replace a Schottky diode. When used in diode-OR and high current diode applications, the LTC4357HDCB#TRMPBF reduces power consumption, heat dissipation, voltage loss and PC board area.
The LTC4357HDCB#TRMPBF easily ORs power sources to increase total system reliability. In diode-OR applications, the LTC4357HDCB#TRMPBF controls the forward voltage drop across the MOSFET to ensure smooth current transfer from one path to the other without oscillation. If the power source fails or is shorted, a fast turn-off minimizes reverse current transients.
- Reduces Power Dissipation by Replacing a Power Schottky Diode with an N-Channel MOSFET
