The TPS2115PWRG4 from Texas Instruments is an innovative power management integrated circuit that provides an efficient auto-switching solution between two power sources. This device is designed for applications where continuous power supply is critical, and it ensures seamless transition between sources without interruption to the load.

Key Features

• Automatic Switching: The TPS2115PWRG4 can automatically select between two power sources, prioritizing the higher voltage source to supply power to the load.
• Voltage Range: It operates across a wide voltage range from 2.8V to 5.5V, making it suitable for various applications, including portable devices and industrial systems.
• Low R<sub>ON: Features a low on-resistance of typically 50 mΩ, which minimizes power loss and maximizes efficiency.
• Cross-Conduction Block: The built-in circuitry prevents cross-conduction during the transition between power sources.
• Power Good Outputs: Offers two ‘power good’ outputs, one for each source, which can be used to enable or disable other system components based on the presence of a valid input supply.
• Thermal and Overcurrent Protection: Incorporates safety features such as thermal shutdown and overcurrent protection to safeguard the device and the system in adverse conditions.
