REVISION HISTORY
Changes from Original (February 2010) to Revision A Page
Changed the data sheet From: Preview To: Production Data .............................................................................................. 1
Changed the Overview section - paragraph 2 From: MOSFET gate is initially low, and V
(AC)
is less than 64 mV. To:
MOSFET gate is initially at GND, and V
(A-C)
is less than 65 mV. ........................................................................................ 10
Changed the Overview section - paragraph 2, From: The TPS2419 turns on the MOSFET gate, and charges it to
V
(BYP)
once the turn-on threshold is exceeded. To: When the turn-on threshold is exceeded, the TPS2419 turns on
the MOSFET gate, and charges it to V
(BYP)
........................................................................................................................ 10
Changed the Overview section - paragraph 3 From: The ORed input supply will experience a momentary large load
as the MOSFET turns on, shorting the internal diode and charging the bus capacitance. To: The ORed input supply
will experience a momentary large current draw as the MOSFET turns on, shorting the internal diode and charging
the bus capacitance. ........................................................................................................................................................... 10
Changed the RECOMMENDED OPERATING RANGE section, paragraph 1 From: The TPS2419 will operate
properly up to the absolute maximum voltage ratings on A, C, and V
DD
. To: The TPS2419 will operate properly up to
the absolute maximum voltage ratings on A and C. ........................................................................................................... 12
