TPS2053D

Power Distribution Switches, Load Drivers Overview

The TPS2053D is a single-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 features an integrated current limit of 345 mA. The device utilizes an N-channel MOSFET topology and is housed in an 8-pin SOIC package. Key electrical parameters include a maximum on-resistance of 130 mΩ and a typical turn-on time of 60 μs. It supports active-high enable control and includes fault reporting capabilities via a status flag.

Power Distribution Switches, Load Drivers Feature Summary

• Integrates overcurrent, thermal, and under-voltage lockout protection mechanisms for robust system management.
• Provides a dedicated fault status flag output to indicate latch-off conditions caused by excessive current or temperature.
• Features a low on-state resistance to minimize power dissipation during normal operation.

Power Distribution Switches, Load Drivers Applications

• Portable computing devices requiring protected power rails
• Consumer electronics with hot-swappable peripheral interfaces
• Industrial control systems needing reliable load switching

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'D' corresponds to the standard SOIC-8 tape and reel packaging configuration as defined in the official datasheet. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure the operating temperature range aligns with your environmental specifications before finalizing procurement orders.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a single-channel high-side switch with moderate current capacity is required. It is suitable for applications needing built-in fault protection without external sensing components. Consider the SOIC package size constraints and the 2.7V minimum operating voltage when designing the power architecture.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the TPS205x family of power distribution switches designed for protecting loads in portable and industrial equipment. It offers a compact solution for managing power delivery while providing diagnostic feedback through its status pin, simplifying system monitoring and error handling in complex electronic designs.

Power Distribution Switches, Load Drivers Replacement Considerations

Direct substitutes include the TPS2053AD (SOIC-16) and TPS2053DR (SOIC-8). Verify pin compatibility and current ratings when replacing with these variants to ensure proper functionality within the existing circuit layout.
