The LTC4354 is a negative voltage diode-OR controller designed by LT to drive two external N-channel MOSFETs. This component effectively replaces two Schottky diodes and their associated heat sinks, leading to significant power and area savings. The use of N-channel MOSFETs as pass transistors greatly reduces power dissipation.
Key features include operation up to 80V and a fast turn-off time of less than 1µs, which limits peak fault current and prevents damage to pass transistors. The LTC4354 ensures smooth transfer of current between power sources without oscillation. It also includes a fault detection circuit with an open-drain output to indicate MOSFET or supply failures.
Applications for the LTC4354 include AdvancedTCA systems, -48V distributed power systems, computer systems/servers, telecom infrastructure, and optical networks. It is available in an 8-lead DFN (3mm x 2mm) package and an 8-lead SO package, with operating temperature ranges of 0°C to 70°C and -40°C to 85°C respectively.
