Control External FET for N+1 and ORing

Controls Buses From 0.8 V to 16.5 V  
Linear or On/Off Control Method  
DESCRIPTION  
The TPS2412/13 controller, in conjunction with an  
external N-channel MOSFET, emulates the function  
of a low forward voltage diode. The TPS2412/13 can  
be used to combine multiple power supplies to a  
common bus in an N+1 configuration, or to combine  
redundant input power buses. The TPS2412 provides  
a linear turn-on control while the TPS2413 has an  
on/off control method.  
Internal Charge Pump for N-Channel MOSFET  
Rapid Device Turnoff Protects Bus Integrity  
Positive Gate Control on Hot Insertion  
Soft Turn on Reduces Bus Transients  
Industrial Temperature Range: –40°C to 85°C  
8-Pin TSSOP and SOIC Packages  
Applications for the TPS2412/13 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. A TPS2412/13 and N-channel MOSFET  
provide this function with less power loss than a  
schottky diode.
