Overview of Texas Instruments TPS2113PWR

The Texas Instruments TPS2113PWR is a versatile power multiplexer that allows seamless transition between two power sources, making it an ideal solution for dual-supply systems. This component is part of the AutoSwitch™ family of power multiplexers, which are designed to automatically switch between two power sources without interruption to the load.

Key Features

• Wide Voltage Range: The TPS2113PWR operates over a broad voltage range from 2.8V to 5.5V, making it suitable for various applications, including battery-powered devices.
• Current Limiting: It features built-in current limiting, which protects the device from overcurrent conditions, enhancing system reliability.
• Low On-Resistance: The low on-resistance (rON) of the internal FET switch ensures high efficiency and minimal voltage drop across the switch, preserving energy in battery-operated systems.
• Break-Before-Make Switching: The TPS2113PWR employs break-before-make switching to prevent cross-conduction and shorting between the supplies during transitions.
• Power Good Outputs: It includes two open-drain power-good outputs, one for each input source, providing a straightforward way to monitor the status of the power supplies.
