TPS2115APWRG4

Overview

The TPS2115APWRG4 is an autoswitching power multiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 2.8 V to 5.5 V and features an N-channel internal switch with a maximum on-resistance of 110 mOhms. The device supports an output current of 1.25 A and includes adjustable current limiting from 630 mA to 2 A. Key timing parameters include a maximum turn-on delay of 1 ms and a maximum turn-off delay of 5 ms. It is housed in an 8-TSSOP package and functions as a source selector switch for power distribution.

• Low on-resistance N-channel switch

Applications

• Handheld devices
• Mobile equipment
• Power distribution systems

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status against the manufacturer's official documentation. Confirm the TSSOP-8 package dimensions and pinout match the design requirements. Ensure the operating temperature range of -40°C to +85°C aligns with the environmental conditions of the target application. Cross-reference the datasheet revision history for any recent parameter updates or packaging changes.

Selection Notes

Select this component when a single output must be sourced from two inputs with automatic switching based on voltage levels. Consider the 110 mOhms on-resistance for efficiency calculations and the 1.25 A output current limit for load requirements. The adjustable current limit allows protection tuning between 630 mA and 2 A. Evaluate the 1 ms turn-on time for system startup sequencing needs.

Part Context

This part belongs to the TPS2115A series of autoswitching power muxes from Texas Instruments. It is designed for efficient power path management in portable electronics. The device simplifies battery backup and charging circuit designs by automatically selecting the best available power source without external control logic.
