Overview
The TPS2113PW is an autoswitching power multiplexer manufactured by Texas Instruments, designed for efficient power distribution in portable electronics. It features a single output derived from two independent inputs, supporting a maximum continuous output current of 1.25 A with configurable current limiting ranging from 630 mA to 2 A. The device operates within a supply voltage range of 2.8 V to 5.5 V and maintains a maximum on-resistance of 110 mOhms. It utilizes an 8-pin TSSOP package and functions reliably across an extended temperature range from -40°C to +85°C.
Feature Summary
- Autoswitching logic automatically selects the optimal input source based on voltage levels without external control signals
- Configurable current limit protection allows adjustment between 630 mA and 2 A to safeguard downstream loads
- Low on-resistance minimizes power loss and thermal generation during conduction
Applications
- Battery-powered handheld devices requiring seamless power source switching
- Portable equipment utilizing multiple power inputs such as AC adapters and batteries
- Systems needing protected power distribution with automatic source selection
Procurement Notes
Verify the specific suffix 'PW' confirms the 8-TSSOP package variant when sourcing. Confirm RoHS compliance status matches project requirements. Ensure the selected distributor provides genuine Texas Instruments components to avoid counterfeit risks. Check datasheet revisions for any marking or assembly changes that may affect integration.
Selection Notes
Select this component when an autoswitching function is required without GPIO control overhead. Compare against TPS2112A if lower current ratings suffice, as the TPS2113 offers higher current capacity. Consider the TPS2113ADRBR for applications requiring a smaller 8-SON footprint instead of the TSSOP package.
Part Context
This part belongs to the TPS211xA family of autoswitching power muxes from Texas Instruments. It serves as a high-current alternative to the TPS2112A, providing enhanced load handling capabilities while maintaining similar low-power standby characteristics. The family targets mobile and portable markets where space and efficiency are critical constraints.
Replacement Considerations
TPS2112A offers similar functionality but with reduced current capacity (0.75 A). For identical performance in a different package, consider TPS2113APWR (TSSOP) or TPS2113ADRBR (SON).
