The part's current-limiting protection is adjustable, so you set the threshold above the steady-state load but below the 70 A ceiling. Continuous current at 70 A would exceed the package's thermal limits within seconds — the datasheet's safe-operating-area curve tells you the pulse width vs. current trade-off. ## AEC-Q100 grade-1 — underhood-ready The OEM auditor will ask for the PPAP documentation, and the AEC-Q100 stamp on the series is the first gate passed. Capable is not qualified; this part carries the qualification. ## Fault protection set — what it catches The protection block covers current limiting (adjustable), over-current, over-temperature, reverse current, and undervoltage lockout. Reverse current protection is notable — it blocks back-feed from the load when the supply drops, a common failure mode in automotive battery-line switches. The adjustable current limit lets you tailor the trip point to the load wire gauge and fuse coordination. The 3 V to 28 V supply range covers 12 V automotive systems directly, including cold-crank down to 3 V and load-dump transients up to 28 V. No external pre-regulator is needed for the control logic — the Vcc/Vdd pin powers the internal charge pump and gate drive from the same rail as the load. ## Active lifecycle — no obsolescence watch This is a current-generation part that can be qualified into a new BOM without imminent obsolescence risk.","metaTitle":"TPS1HB08AQPWPRQ1 Automotive High-Side Switch, 8 mOhm, 70A","metaDescription":"Texas Instruments TPS1HB08AQPWPRQ1 automotive AEC-Q100 high-side switch, 8 mOhm Rds(on), 70A peak, -40 to 125°C.
