TPS2419 Datasheet | Texas Instruments

FEATURES - Control External FET for N+1 and ORing - Controls Buses From 3 V to 16.5 V - External Enable - N-Channel MOSFETControl - Rapid Device Turnoff Protects Bus Integrity - Programmable Turn-Off Threshold - Soft Turn on Reduces Bus Transients - Industrial Temperature Range: - 40°C to 85°C - 8-Pin TSSOP and SOIC Packages APPLICATIONS - N+1 Power Supplies - Server Blades - Tele Systems - High Availability Power Modules DESCRIPTION The TPS2419 controller, in conjunction with an external N-channel MOSFET, provides the reverse current protection of an ORing diode with the efficiency of a MOSFET. The TPS2419 can be used to bine multiple power supplies to a mon bus in an N+1 configuration, or to bine redundant input power buses. Applications for the TPS2419 include a wide range of systems including servers and tele. These applications often have either N+1 redundant power supplies, redundant power buses, or both. Redundant power sources must have the equivalent of a diode OR to prevent reverse current during faults and hotplug. Accurate voltage sensing and a programmable turn-off threshold allows operation to be tailored for a wide range of implementations and bus characteristics. The TPS2419 brings out an enable pin which allows the system to force the MOSFET off under light-load, high noise conditions.
