Overview
The TPS2111APWG4 is an autoswitching power multiplexer manufactured by Texas Instruments. It features a TSSOP-8 package and supports two input channels with one output channel. The device operates within an input voltage range of 2.8V to 5.5V. It includes adjustable threshold functionality for source selection. The component is designed for power distribution applications requiring automatic switching between power sources.
Feature Summary
- Autoswitching power multiplexer functionality
- Adjustable threshold for source selection
- Supports low voltage operation down to 1.5V under specific conditions
Applications
- Power distribution systems
- Battery backup switching
- Dual power source management
Procurement Notes
Verify the component authenticity through authorized Texas Instruments distributors or certified partners. Confirm the package marking matches the TSSOP-8 specification. Ensure the RoHS compliance status aligns with project requirements. Check for any specific ordering suffixes that may affect packaging or temperature rating. Validate the datasheet revision against the current official documentation.
Selection Notes
Select this component when an autoswitching power mux is required for dual-source applications. Consider the 2.8V minimum input voltage constraint. Evaluate the need for adjustable thresholds in the design. Compare performance against similar models like TPS2110 or TPS2112A if different current ratings are needed. Ensure the TSSOP-8 package fits the PCB layout constraints.
Part Context
The TPS2111APWG4 belongs to the TPS211x series of autoswitching power multiplexers from Texas Instruments. This family provides solutions for seamless switching between two power inputs. The device simplifies power path management in portable and industrial electronics. It integrates control logic to manage source selection automatically based on voltage levels.
Replacement Considerations
The TPS2111APWR is a non-green equivalent. The TPS2111APW is a leaded version. Verify pin compatibility and electrical specifications before substitution.
