TPS2114PW Power Multiplexer from Texas Instruments

The TPS2114PW from Texas Instruments is a versatile power multiplexer that enables seamless transition between two power sources in a variety of electronic applications. This advanced IC is designed to prioritize a primary power source over a secondary one, ensuring that devices remain operational even when the primary source fails or is disconnected.

Key Features:

• Automatic Switching: The TPS2114PW automatically switches to the secondary power source when the primary source voltage drops below a certain threshold, without interrupting the supply to the load.
• Wide Voltage Range: It operates over a wide supply voltage range, typically from 2.8V to 5.5V, making it suitable for a broad range of applications.
• Bidirectional Operation: The device supports bidirectional current flow, which is essential for applications such as battery charging and power-path management.
• Low RON: With a low on-resistance (RON) of typically 85mΩ, the TPS2114PW ensures minimal voltage drop and power loss during operation.
• Break-Before-Make Switching: The internal break-before-make architecture prevents cross-conduction when transitioning between sources.
• Status Flag: An open-drain power-good output provides a status flag that indicates when a valid power source is present.

Applications:

The TPS2114PW is ideal for a range of applications, including but not limited to:

• Redundant power supplies
• Power-path controllers
• Portable devices with dual power sources
• Battery-powered equipment
• Hot-swapping and plug-and-play applications

Reliability and Packaging:

Encased in a 14-pin TSSOP (Thin Shrink Small Outline Package), the TPS2114PW is designed for space-constrained applications, while providing robust protection features such as under-voltage lockout (UVLO), over-current protection, and thermal shutdown. Its compact form factor and high level of integration make it a reliable choice for designers looking to create systems with seamless power-source management.

With the TPS2114PW, Texas Instruments continues to provide innovative solutions that enhance the performance and reliability of electronic systems worldwide.
