Product Summary
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. Accurate voltage sensing and a programmable turn-off threshold allows operation to be tailored for a wide range of implementations and bus characteristics. The TPS2419 brings out an enable pin which allows the system to force the MOSFET off under light-load, high noise conditions.
Parametrics
TPS2419 absolute maximum ratings: (1)A, C voltage: –0.3 to 18 V; (2)A above C voltage: 7.5 V; (3)C above A voltage: 18 V; (4)GATE, BYP voltage(2): –0.3 to 30 V; (5)BYP to A voltage: –0.3 to 13 V; (6)GATE above BYP voltage: 0.3 V; (7)RSET(2) voltage: –0.3 to 7 V; (8)EN: –0.3 to 5.5 V; (9)GATE short to A or C or GND: Indefinite.
