TPS2561DRCR

Power Distribution Switches, Load Drivers Overview

The TPS2561DRCR is a dual-channel precision adjustable current-limited power switch manufactured by Texas Instruments. It features an N-channel output configuration with a maximum continuous output current of 2.5 A per channel. The device supports an input voltage range of 2.5 V to 6.5 V and offers an adjustable current limit ranging from 250 mA to 2.8 A. Key electrical parameters include a maximum on-resistance of 50 mOhms, a maximum rise time of 9 ms, and a maximum fall time of 6 ms. It operates within a temperature range of -40°C to +85°C and is housed in a 10-VSON (3x3) surface-mount package.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'DRCR' corresponds to the standard commercial grade variant rather than automotive or industrial extended temperature grades. Confirm the package marking matches the 10-VSON footprint dimensions. Ensure ESD handling protocols are followed during assembly due to the exposed pad thermal design. Cross-reference the datasheet revision date to confirm pinout compatibility with existing PCB layouts.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when dual independent channels are required within a compact footprint. The adjustable current limit allows customization for varying load requirements without external resistors. Consider the 50 mOhms on-resistance for efficiency calculations. Verify that the 2.5 A per channel rating meets peak load demands. Evaluate the controlled slew rate benefits against system inrush constraints compared to fixed-rate alternatives.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the TPS256x family of power switches designed for USB and general-purpose load switching applications. It complements single-channel variants like the TPS255x series and higher-current eFuse solutions. The dual-channel design simplifies bill-of-materials for systems requiring multiple protected power rails. It serves as a robust alternative to discrete MOSFET and protection circuit implementations.

Power Distribution Switches, Load Drivers Replacement Considerations

The TPS2561DRCTQ1 is a qualified automotive-grade alternative within the same family. The TPS2560DRCR offers similar dual-channel functionality but may differ in specific current limit ranges or feature sets. Verify pin-to-pin compatibility before substitution. Check if the replacement part meets the required operating temperature range and current specifications.
