TPS2226DB

Power Distribution Switches, Load Drivers Overview

The TPS2226DB is a single-channel power switch manufactured by Texas Instruments, designed for load switching applications. It operates within an input voltage range of 1.6V to 5.5V and supports a continuous output current of up to 1A. The device features a low on-resistance of 0.3 ohms typical value, ensuring efficient power delivery with minimal voltage drop. It incorporates adjustable soft-start capabilities to limit inrush current during startup, protecting both the source and the load. The component is housed in a compact 6-pin SOT-23 package, suitable for space-constrained designs. It functions reliably across an extended industrial temperature range from -40°C to +85°C.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'DB' corresponds to the SOT-23-6 package variant when sourcing. Confirm that the selected distributor provides components with intact moisture barrier packaging to preserve lead integrity. Ensure the procurement channel is authorized to guarantee authenticity and traceability of the Texas Instruments manufacturing lot. Cross-reference the date code to ensure compliance with current RoHS directives if required by your assembly specifications.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a single-channel solution with integrated protection is required for loads drawing up to 1A. It is appropriate for designs needing precise inrush current control without external timing components. Consider the low on-resistance for minimizing power loss in battery-operated devices. Evaluate the thermal performance in the SOT-23 package relative to the expected ambient temperature and duty cycle of the application.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the TPS222x series of power switches, which are optimized for portable applications. The series offers various configurations including single and dual channels with different current ratings. The TPS2226 represents the single-channel variant within this family, providing a balance between performance and footprint.
