TPS2052BDGN

Power Distribution Switches, Load Drivers Overview

The TPS2052BDGN is a dual-channel, current-limited power-distribution switch manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and features an active-high enable input. The device provides fixed current limiting at 1 A with a typical on-resistance of 135 mOhms. It incorporates comprehensive fault protection mechanisms including thermal shutdown, under-voltage lockout (UVLO), and reverse battery protection. The component is housed in an 8-pin MSOP-PowerPad package and supports an operating temperature range from -40°C to +85°C.

Power Distribution Switches, Load Drivers Feature Summary

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'G' against the manufacturer's official documentation to confirm the exact tape-and-reel quantity and packaging configuration. Ensure the selected variant matches the required lead time and availability status for your production schedule. Cross-reference the datasheet revision to confirm compliance with RoHS standards and environmental regulations applicable to your region.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when dual-channel high-side switching with integrated current limiting is required. It is suitable for applications needing protection against short circuits and thermal overload. Consider the 135 mOhms on-resistance for efficiency calculations. Verify that the 1 A current limit aligns with load requirements and that the MSOP-8 package fits the PCB layout constraints.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the TPS2052 family of power-distribution switches designed for USB and general-purpose power routing. It complements single-channel variants like the TPS2051 and higher-current models within the same product line. The family shares common interface protocols and protection features, allowing for scalable design architectures across different power distribution needs.

Power Distribution Switches, Load Drivers Replacement Considerations

The TPS2052BDG is a direct pin-compatible alternative without the 'N' suffix, typically available in tube packaging instead of reel. Other family members such as the TPS2052AD or TPS2052BDRBT offer similar functionality but may differ in current limits, on-resistance, or package type.
