SLVS727C–NOVEMBER 2006–REVISED JUNE 2009 Full Featured N+1 and ORing Power Rail Controller 1 FEATURES DESCRIPTION • Control External FET for N+1 and ORing The TPS2410/11 controller, in conjunction with an • Wide Supply Voltage Range of 3 V to 16.5 V external N-channel MOSFET, emulates the function • Controls Buses From 0.8 V to 16.5 V of a low forward-voltage diode. The TPS2410/11 can • Linear or On/Off Control Method be used to combine multiple power supplies to a common bus in an N+1 configuration, or to combine • Internal Charge Pump for N-Channel MOSFET redundant input power buses. The TPS2410 provides • Rapid Device Turnoff Protects Bus Integrity a linear turn-on control while the TPS2411 has an • Positive Gate Control on Hot Insertion on/off control method. • Soft Turn on Reduces Bus Transients Applications for the TPS2410/11 include a wide range • Input Voltage Monitoring of systems including servers and telecom. These applications often have either N+1 redundant power • Shorted Gate Monitor supplies, redundant power buses, or both. These • MOSFET Control-State Indicator redundant power sources must have the equivalent of • Industrial Temperature Range: –40°C to 85°C a diode OR to prevent reverse current during faults and hotplug. A TPS2410/11 and N-channel MOSFET • Industry-Standard 14-Pin TSSOP Package provide this function with less power loss than a schottky diode. APPLICATIONS • N+1 Power Supplies Accurate voltage sensing, programmable fast turn-off threshold, and input filtering allow operations to be • Server Blades tailored for a wide range of implementations and bus • Telecom Systems characteristics. • High Availability Systems A number of monitoring features are provided to indicate voltage bus UV/OV, ON/OFF state, and a A C shorted MOSFET gate.
