TPS2553DRVR

Power Distribution Switches, Load Drivers Overview

The TPS2553DRVR is a single-channel USB current-limited power distribution switch manufactured by Texas Instruments. It supports an input voltage range of 2.5 V to 6.5 V and delivers up to 1.5 A continuous load current. The device features a programmable current limit adjustable from 75 mA to 1.7 A via an external resistor, with accuracy reaching ±6% at higher settings. Key electrical parameters include a maximum on-resistance of 115 mΩ, a maximum turn-on time of 3 ms, and a maximum blanking time of 3 ms. It operates within a temperature range of -40°C to +85°C and is housed in a WSON-6 surface-mount package.

Power Distribution Switches, Load Drivers Feature Summary

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'DRVR' against the manufacturer's official datasheet to confirm the exact package variant and tape-and-reel specifications. Ensure the selected component matches the required thermal performance and pinout configuration for your PCB layout. Cross-reference the ordering information with the latest Texas Instruments documentation to avoid discrepancies in marking or material compliance.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when designing circuits requiring adjustable current limiting for USB peripherals or sensitive digital loads. It is suitable for applications needing robust protection against short circuits and reverse polarity without external discrete components. Consider the WSON-6 package size constraints and the need for an external programming resistor when finalizing the bill of materials.

Power Distribution Switches, Load Drivers Part Context

This device belongs to the TPS2553 series of USB current-limited power switches from Texas Instruments. The series is designed for power distribution in consumer electronics and communication equipment. The DRVR suffix indicates a specific packaging and handling configuration within the broader product family, distinguishing it from other variants like the DBVR or DDBVT which may use different packages such as SOT-23-6.

Power Distribution Switches, Load Drivers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify compatibility with alternative TI models such as the TPS2553DBVR or TPS2553DDBVT only if they meet identical electrical and mechanical specifications.
