TPS2064DRBR

Power Distribution Switches, Load Drivers Overview

The TPS2064DRBR is a dual-channel high-side power switch IC from Texas Instruments, designed for USB power distribution. It features an output current of 1.5 A per channel with a maximum on-resistance of 70 mOhms. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports a junction temperature range of 0°C to 105°C. Packaged in an 8-SON (3x3) surface-mount format, it integrates fixed current limiting, overtemperature protection, reverse current blocking, and undervoltage lockout.

Power Distribution Switches, Load Drivers Feature Summary

• Dual-channel high-side switching capability with independent control inputs
• Integrated fault protection including fixed current limit, thermal shutdown, and reverse current blocking
• Low on-resistance design for efficient power delivery and minimal voltage drop

Power Distribution Switches, Load Drivers Applications

• USB hub power distribution circuits
• Peripheral port protection in consumer electronics
• Hot-swap applications requiring controlled power sequencing

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix DRBR corresponds to the tape-and-reel packaging configuration rather than tube packaging when sourcing components. Confirm that the 8-SON package variant matches the footprint requirements of the target PCB layout. Ensure compatibility with the specified 2.7 V to 5.5 V operating voltage range for the intended system architecture.

Power Distribution Switches, Load Drivers Selection Notes

Select this component for designs requiring dual isolated power paths with integrated protection. The low on-resistance minimizes power loss compared to higher resistance alternatives. Consider the thermal performance in the small SON package when determining heat dissipation strategies for continuous load conditions.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the TPS206x family of power switches, which provides robust protection for downstream loads. It complements other variants like the TPS2064CDGN by offering different packaging options while maintaining identical electrical characteristics and protection features for consistent system design across form factors.

Power Distribution Switches, Load Drivers Replacement Considerations

TPS2064DRBT is a direct equivalent in the same family with identical pinout and specifications but may differ in reel quantity or specific manufacturing lot details.
