The TPS2111APWRG4 from Texas Instruments is an innovative power management component that offers seamless transition between two power sources. It is designed to enhance the reliability of a system by automatically switching to a secondary power source when the primary source fails or is disconnected. This auto-switching power multiplexer is particularly useful in applications that require a constant power supply without interruption.

Key Features

• Automatic Switching: The device can automatically switch between two voltage sources, ensuring a stable power supply to the load.
• Wide Voltage Range: It operates across a wide voltage range, from 2.8V to 5.5V, making it versatile for various applications.
• Low On-Resistance: The TPS2111APWRG4 features a low ON-resistance of typically 50 mΩ, which helps to minimize voltage drop and power loss.
• Current Limiting: Built-in current limiting protects the device and the load from excessive current draw.
• Cross-Conduction Blocking: The device prevents cross-conduction when switching between sources.
• Power Good Outputs: The TPS2111APWRG4 provides power good outputs that can be used to indicate which source is currently active.

Applications

The TPS2111APWRG4 is suitable for a wide range of applications, including:

• Redundant power supply systems
• Battery-powered devices with a backup power source
• Hot-pluggable devices
• Systems that require power-source ORing
