The LTC4357MPMS8#PBF 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 controller reduces power consumption, heat dissipation, voltage loss and PC board area. The controller easily ORs power sources to increase total system reliability. In diode-OR applications, the controller 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.
- Smooth switchover without oscillation
- No reverse DC current
- 0.5μs Turn-off time limits peak fault current
