Product Overview

The LTC4355IS#PBF is a positive voltage Ideal Diode-OR Controller with input supply and fuse monitor. Forming the diode-OR with N-channel MOSFETs instead of Schottky diodes reduces power consumption, heat dissipation and PC board area. With the LTC4355, power sources can easily be ORed together to increase total system reliability. The LTC4355 can diode-OR two positive supplies or the return paths of two negative supplies, such as in a -48V system. In the forward direction the LTC4355 controls the voltage drop across the MOSFET to ensure smooth current transfer from one path to the other without oscillation. If a power source fails or is shorted, fast turnoff minimizes reverse current transients. Power fault detection indicates if the input supplies are not in regulation, the inline fuses are blown or the voltages across the MOSFETs are greater than the fault threshold.
  • Controls N-Channel MOSFETs
  • 0.3µs Turn-OFF time limits peak fault current
  • Smooth switchover without oscillation
  • No reverse DC current
  • Monitors VIN, fuse and MOSFET diode
  • Green product and no Sb/Br
