TPS2121RUXR General Description

The TPS2121RUXR is a power multiplexer IC that enables switching between two different power sources or inputs, providing a seamless transition between them. This functionality is useful in scenarios where redundancy or load sharing between power sources is required to ensure continuous operation and reliability.

Key Features

  • Dual Input Power Multiplexer: The TPS2121RUXR allows you to connect two different power sources (e.g., batteries, power supplies) and seamlessly switch between them based on the input voltage conditions.
  • Low Quiescent Current: The IC is designed to minimize power consumption when operating, making it suitable for battery-powered applications where power efficiency is crucial.
  • Reverse Current Blocking: It includes reverse current blocking to prevent current from flowing back into the inactive input source.
  • Wide Input Voltage Range: The IC typically supports a wide input voltage range, allowing it to work with various power supply voltages.
  • Power-On Reset (POR) Function: The TPS2121RUXR may include a POR function that monitors the input voltage levels and generates a reset signal to ensure proper startup sequencing.
  • Protection Features: Some models of the IC may include protection features such as overvoltage protection (OVP) and thermal shutdown.

Soldered back to the place of burned utc2030 on the amplifier nakatomi GS-35. Everything works as it should. It came in a normal package with a "puffy", but everything works and even the legs are not bent.
