Key Features
- AEC-Q100 automotive qualification supporting -40°C to 125°C operation for in-vehicle power rail protection
- Dual independent channels each supporting up to 2.5 A continuous current with adjustable overcurrent threshold via external resistor
- Fast 1 ms controlled rise time with soft-start limits inrush current, protecting downstream capacitive loads on 2.5 V to 6.5 V rails
Applications
TPS2561AQDRCTQ1 is designed for automotive infotainment, ADAS camera modules, and telematics units requiring dual independent power switch control on 3.3 V and 5 V rails. Its adjustable current limit and AEC-Q100 Grade 1 rating make it suitable for USB port power management and peripheral load switching in head units operating across -40°C to 125°C. The compact 10-pin VSON 3 mm × 3 mm footprint fits space-constrained automotive PCB designs with multiple load switch requirements.

Frequently Asked Questions
What is the maximum current per channel on TPS2561AQDRCTQ1 and how is the limit set?
TPS2561AQDRCTQ1 supports up to 2.5 A per channel. The overcurrent threshold is adjustable via an external resistor connected to the ILIM pin, allowing designers to set thresholds from approximately 200 mA to 2.5 A to match different load requirements on 2.5 V to 6.5 V rails.
Which automotive applications benefit most from TPS2561AQDRCTQ1's dual-channel design?
Automotive ADAS modules, USB charging ports, and infotainment systems benefit from TPS2561AQDRCTQ1's 2 independent 2.5 A channels, allowing separate enable control for camera sensors and audio amplifiers on the same 5 V rail while maintaining AEC-Q100 Grade 1 compliance from -40°C to 125°C.
How does TPS2561AQDRCTQ1 prevent inrush current damage when enabling capacitive loads?
TPS2561AQDRCTQ1 uses a controlled 1 ms soft-start rise time that limits inrush current into large bypass capacitors. For a 100 µF output capacitor on a 5 V rail, the controlled slew rate keeps inrush below the 2.5 A current limit, preventing false overcurrent trips at power-up.
What package size and footprint does TPS2561AQDRCTQ1 use in space-constrained automotive PCB designs?
TPS2561AQDRCTQ1 uses a 10-pin VSON package with a 3 mm × 3 mm body and 0.9 mm height, enabling compact dual-channel load switch integration on automotive PCBs where board area per function must stay below 10 mm².
