Working Principles

The TPS2111PW is designed to multiplex power sources, allowing seamless switching between two input power sources. It automatically selects the highest priority available power source and routes it to the output. The device continuously monitors the input voltages and switches to the alternate source if the primary source becomes unavailable or falls outside the acceptable voltage range. It provides protection against overvoltage and undervoltage conditions, ensuring a stable output voltage.

Detailed Application Field Plans

The TPS2111PW finds applications in various fields where power source redundancy and seamless switching are crucial. Some of the detailed application field plans include:

1. Portable Electronics: Enables uninterrupted power supply during battery charging or swapping.
2. Industrial Automation: Provides reliable power source selection for critical control systems.
3. Automotive Electronics: Ensures continuous operation by seamlessly switching between multiple power sources.
4. Medical Devices: Offers redundant power options for critical medical equipment.
5. Telecommunications: Facilitates uninterrupted power supply during power source failures.
