TPS2113ADRBR General Description

The TPS211xA family of power multiplexers enables seamless transition between two power supplies (such as a battery and a wall adapter), each operating at 2.8 V to 5.5 V and delivering up to 2 A, depending on package. The TPS211xA family includes extensive protection circuitry, including user-programmable current limiting, thermal protection, inrush current control, seamless supply transition, cross-conduction blocking, and reverse-conduction blocking. These features greatly simplify designing power multiplexer applications.

Key Features

Two-Input, One-Output Power Multiplexer with Low r_DS(on) Switches:
- 84 mΩ Typ (TPS2113A)
- 120 mΩ Typ (TPS2112A)
Reverse and Cross-Conduction Blocking
Wide Operating Voltage: 2.8 V to 5.5 V
Low Standby Current: 0.5 µA Typ
Low Operating Current: 55 µA Typ
Adjustable Current Limit
Controlled Output Voltage Transition Time:
- Limits Inrush Current
- Minimizes Output Voltage Hold-Up Capacitance
CMOS- and TTL-Compatible Control Inputs
Auto-Switching Operating Mode
Thermal Shutdown
Available in TSSOP-8 and 3-mm × 3-mm SON-8 Packages
