1FEATURES APPLICATIONS Two-Input, One-Output Power Multiplexer with • PCs
Low rDS(on) Switches: • PDAs 84 mΩ Typ (TPS2113A) • Digital Cameras 120 mΩ Typ (TPS2112A) • Modems Reverse and Cross-Conduction Blocking • Cell Phones Wide Operating Voltage: 2.8Vto 5.5V • Digital Radios Low Standby Current: 0.5 μA Typ • MP3 Players Low Operating Current:55 μA Typ
DESCRIPTION• Adjustable Current LimitThe TPS211xA familyof power multiplexers enables
• Controlled Output Voltage Transition Time: seamless transition between two power supplies
– Limits Inrush Current (such asa battery anda wall adapter), each
Minimizes Output Voltage Hold-Up operatingat 2.8Vto 5.5V and delivering upto2A,
depending on package. The TPS211xA family
Capacitanceincludes extensive protection circuitry, including user-
• CMOS- and TTL-Compatible Control Inputs programmable current limiting, thermal protection,
• Auto-Switching Operating Mode inrush current control, seamless supply transition,
Thermal Shutdown cross-conduction blocking, and reverse-conduction
blocking. These features greatly simplify designing
• Availablein TSSOP-8 and 3-mm× 3-mm SON-8 power multiplexer applications.
