N+1 and ORing Power Rail Controller
Control External FET for N+1 and ORing
Wide Supply Voltage Range of 3 V to 16.5 V
The TPS2412/13 controller, in conjunction with an
Controls Buses From 0.8 V to 16.5 V
external N-channel MOSFET, emulates the function
Linear or On/Off Control Method
of a low forward voltage diode. The TPS2412/13 can
be used to combine multiple power supplies to a
Internal Charge Pump for N-Channel MOSFET
common bus in an N+1 configuration, or to combine

redundant input power buses. The TPS2412 provides
Positive Gate Control on Hot Insertion
a linear turn-on control while the TPS2413 has an
on/off control method.
Soft Turn on Reduces Bus Transients
Industrial Temperature Range: –40°C to 85°C
Applications for the TPS2412/13 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
power sources must have the equivalent of a diode

provide this function with less power loss than a
