N+1 and ORing Power Rail Controller with Enable
Checkfor Samples: TPS2419
1FEATURES Control External FET for N+1 and ORing DESCRIPTION Controls Buses From3Vto 16.5V 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 efficiencyofa MOSFET. The TPS2419 can be used•
Rapid Device Turnoff Protects Bus Integrity to combine multiple power suppliestoa common bus
Programmable Turn-Off Threshold in an N+1 configuration, orto combine redundant
input power buses.•
Soft Turn on Reduces Bus Transients Industrial Temperature Range: –40°C
to 85°C Applications for the TPS2419 includea wide rangeof
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 equivalentofa diode
N+1 Power Supplies OR to prevent reverse current during faults and
hotplug.•
Server Blades Telecom Systems Accurate voltage sensing anda programmable
turn-off threshold allows operationto be tailored fora•
High Availability Power Modules wide range of implementations and bus
characteristics. The TPS2419 brings out an enable
pin which allows the systemto force the MOSFET off
under light-load, high noise conditions.
