TPS2062DR-1

Power Distribution Switches, Load Drivers Overview

The TPS2062DR-1 is a dual-channel, high-side power distribution switch manufactured by Texas Instruments. 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 and an on-resistance (Rds(on)) of 70 mOhms. It includes integrated fault protection mechanisms such as overtemperature shutdown, undervoltage lockout (UVLO), and load release functionality. The component is housed in an 8-SOIC package and is designed for surface-mount installation.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'DR-1' against the manufacturer's official datasheet to confirm pinout compatibility and functional equivalence with standard TPS2062 variants. Ensure that the required operating temperature range and package dimensions align with the target PCB layout constraints before finalizing procurement decisions.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when dual-channel high-side switching with precise 1 A current handling is required. The 70 mOhms on-resistance offers lower conduction loss compared to standard 135 mOhms variants. Consider the 8-SOIC package size and the active-low enable logic requirements during circuit design integration.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the TPS2062 family of current-limited power-distribution switches. It provides robust protection for sensitive electronics against short circuits and overcurrent conditions. The series is widely utilized in applications requiring reliable power management for multiple peripheral devices connected to a common bus.

Power Distribution Switches, Load Drivers Replacement Considerations

TPS2062DR: Standard version without the '-1' suffix; verify if the enable logic or internal configuration differs. TPS2062DGNRG4: MSOP-PowerPAD package variant; suitable if space-constrained layouts are required.
