• Control External FET for N+1 and ORing DESCRIPTION

• Controls Buses From 3 V to 16.5 V The TPS2419 controller, in conjunction with an

• External Enable external N-channel MOSFET, provides the reverse

current protection of an ORing diode with the • N-Channel MOSFETControl

efficiency of a MOSFET. The TPS2419 can be used

• Rapid Device Turnoff Protects Bus Integrity to combine multiple power supplies to a common bus

• Programmable Turn-Off Threshold in an N+1 configuration, or to combine redundant

input power buses. • Soft Turn on Reduces Bus Transients

• Industrial Temperature Range: –40°C to 85°C Applications for the TPS2419 include a wide range of

systems including servers and telecom. These • 8-Pin TSSOP and SOIC Packages

applications often have either N+1 redundant power

supplies, redundant power buses, or both. Redundant APPLICATIONS

power sources must have the equivalent of a diode

hotplug. • Server Blades

• Telecom Systems Accurate voltage sensing and a programmable

turn-off threshold allows operation to be tailored for a • High Availability Power Modules

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.
