What is TPS2561QDRCRQ1 used for?
The TPS2561QDRCRQ1 is designed for automotive body electronics and infotainment systems where two independent power rails must be individually current-limited and protected. Its adjustable threshold capability allows fine-tuned overcurrent protection for loads such as USB ports, sensors, and actuators in 12 V automotive platforms. The part is also used in industrial dual-rail power sequencing designs that demand precision current-limit accuracy and thermal robustness.

Frequently Asked Questions
What is the maximum current limit setting for each channel on the TPS2561QDRCRQ1?
Each channel of the TPS2561QDRCRQ1 supports an adjustable current limit reaching up to 2.8 A, set via an external resistor on the ILIM pin. This allows designers to fine-tune overcurrent thresholds for loads ranging from small sensors to higher-power actuators, all within a 2.5 V to 6.5 V input voltage range.
At what temperature does the TPS2561QDRCRQ1 thermal shutdown activate, and why does this matter for automotive use?
The device triggers thermal shutdown at 155°C junction temperature, which is essential for automotive under-hood environments where ambient temperatures can exceed 125°C during peak operation. This protection prevents damage to the 10-pin SON package and downstream loads when transient overcurrent or high ambient conditions occur simultaneously.
How does the TPS2561QDRCRQ1 compare to a single-channel load switch in a dual-rail automotive design?
Integrating two independently controllable channels in one 10-pin SON footprint reduces BOM count and PCB area compared to using two discrete single-channel switches. Both channels operate over the same 2.5 V to 6.5 V supply range with individually adjustable current limits up to 2.8 A, simplifying layout and qualification for AEC-Q100-grade automotive systems.
