TPS2066DR

Power Distribution Switches, Load Drivers Overview

The TPS2066DR is a dual-channel power distribution switch manufactured by Texas Instruments, designed for USB applications. It operates within a supply voltage range of 2.7 V to 5.5 V and supports a continuous output current of 1 A per channel. The device features a fixed current limit of 1.5 A, an on-resistance maximum of 135 mOhms, and a turn-on time of up to 3 ms. Packaged in an SOIC-8 surface-mount format, it functions across a temperature range of -40°C to +85°C.

Power Distribution Switches, Load Drivers Feature Summary

• Dual-channel architecture providing independent control over two separate power paths.
• Integrated constant-current limiting to protect against short circuits and overloads.
• Built-in thermal shutdown and under-voltage lockout for enhanced system reliability.

Power Distribution Switches, Load Drivers Applications

• USB hub power distribution
• Peripheral port protection
• Hot-swappable bus systems

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'DR' indicates tape-and-reel packaging when sourcing. Confirm the manufacturer part number matches exactly to ensure correct SOIC-8 package and electrical specifications. Cross-reference with official datasheets to validate operating temperature ranges and pinout configurations before integration into design.

Power Distribution Switches, Load Drivers Selection Notes

Select this component for designs requiring dual isolated power rails with integrated fault protection. It is suitable for low-voltage logic interfaces where compact surface-mount packaging is preferred. Ensure input voltage stays within the 2.7 V to 5.5 V window to maintain proper operation and avoid undervoltage lockout conditions during startup.

Power Distribution Switches, Load Drivers Part Context

This device belongs to the TPS206x family of power switches, which are optimized for USB compliance. It complements single-channel variants like the TPS2065 and higher-channel options like the TPS2063. The series provides standardized protection features including current limiting and thermal management for portable electronics.

Power Distribution Switches, Load Drivers Replacement Considerations

TPS2066DGN serves as a pin-compatible alternative in MSOP-8 packaging. For automotive applications, consider the qualified TPS2066TDGNRQ1 variant. Verify that substitute parts match the required voltage range and current limits.
