TPS2553DDBVR

Power Distribution Switches, Load Drivers Overview

The TPS2553DDBVR is a single-channel USB current-limited power distribution switch manufactured by Texas Instruments. It operates within a supply voltage range of 2.5 V to 6.5 V and supports an output current of up to 1.5 A. The device features an adjustable current limit ranging from 75 mA to 1.7 A, with a maximum on-resistance of 95 mΩ. It includes controlled slew rate functionality to minimize inrush current and provides status indication via a flag pin. The component is housed in a SOT-23-6 package and is rated for operation between -40°C and +85°C.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'DDBV' corresponds to the SOT-23-6 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to final procurement decisions. Ensure compatibility with surface-mount assembly processes given the small outline transistor package type.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when designing circuits requiring adjustable current limits rather than fixed thresholds. The wide operating voltage range suits various portable applications. Consider the thermal performance characteristics inherent to the SOT-23-6 package for high-current scenarios. Evaluate the need for status flag outputs if system monitoring is required.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the TPS2553 family of USB current-limited power switches. It serves as a high-side switch solution for protecting loads against overcurrent conditions. The series is designed for applications requiring reliable power distribution with minimal external component count. It complements other TI power management solutions for complete system protection strategies.

Power Distribution Switches, Load Drivers Replacement Considerations

TPS2553DRVR is a verified substitute offering identical electrical specifications but packaged in WSON-6 format. Designers must account for footprint differences during PCB layout modifications. Other family members like TPS2551 offer lower current ratings and should be evaluated based on specific load requirements.
