What this part is and where it fits
The Texas Instruments TPS2H000BQPWPRQ1 is an automotive-grade dual-channel high-side power switch with a typical on-resistance of 1 Ohm per channel. Each output is rated for up to 750 mA continuous, and the load supply range spans 3.4 V to 40 V. The switch is controlled by a simple On/Off interface and includes adjustable current limiting and over-temperature protection, plus a status flag output for fault reporting. It comes in a 16-pin PowerTSSOP (HTSSOP) package for surface-mount assembly.
AEC-Q100 qualification and the temperature range it buys you
This part is AEC-Q100 qualified and carries an automotive temperature grade of -40°C to 125°C ambient. That means it is rated for under-hood and cabin-adjacent environments where the PCB sees engine bay heat or direct sunlight through the windshield. The qualification also implies the part has passed the full suite of automotive stress tests — extended life, HAST, temperature cycling — which is the same reason industrial and heavy-equipment buyers often reach for AEC-Q100 parts even when the end product is not a passenger vehicle: the reliability margin is documented.
Sourcing and lifecycle posture
The TPS2H000BQPWPRQ1 is listed as an active, current-production device from Texas Instruments. It is ROHS3 compliant. No end-of-life notification or last-time-buy window has been issued. For a BOM line that needs an automotive-grade high-side switch, this part is a straightforward fit for new designs and production builds.
