Tuotteen yleiskatsaus
Demonstration circuit 2866A features the LTC®4421 dual supply high power prioritized Powerpath™ controller in a 12V/24V, 10A application. LTC4421 incorporates strong gate drivers to switch large external N-channel MOSFETs and fast switchover circuitry to minimize VOUT droop while preventing reverse and cross conduction currents, making it an ideal solution for high reliability systems, battery back up systems and servers. DC2866A arbitrates between two input supply rails, selecting the highest priority, valid supply to power the load. The LTC4421 controls two sets of external back-to-back N-channel MOSFETs to connect the proper rail to the load. Precision comparators are used to monitor each of the two input rails for both UV and OV conditions. The highest priority supply whose voltage is within its respective OV/UV window for time t(VALID) set by the QUAL pin is considered valid and connected to the load.
