N+1 and ORing Power Rail Controller with Enable  
Check for Samples: TPS2419

FEATURES  
Control External FET for N+1 and ORing  
DESCRIPTION  
Controls Buses From 3 V to 16.5 V  
External Enable  
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 combine multiple power supplies to a common bus  
in an N+1 configuration, or to combine redundant  
input power buses.  
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 for the TPS2419 include a wide range of  
systems including servers and telecom. 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.  
APPLICATIONS  
N+1 Power Supplies  
Server Blades  
Telecom Systems  
High Availability Power Modules  
Accurate voltage sensing and  
turn-off threshold allows operation to be tailored for a  
wide range of implementations and bus  
a programmable  
characteristics. The TPS2419 brings out an enable  
pin which allows the system to force the MOSFET off  
under light-load, high noise conditions.
