The TPS1HB50BQPWPRQ1: It switches a 6 V to 18 V load rail through an N-channel MOSFET with a typical on-resistance of 50 mOhm, and can handle continuous output current up to 18 A.
The adjustable current-limiting fault protection lets you set the trip threshold below the 18 A max to protect the load and the switch during short-circuit events.
Yes. The load voltage range is 6 V to 18 V, which covers the nominal 12 V automotive bus with margin for load-dump and cold-crank transients. The AEC-Q100 qualification confirms it is rated for the automotive operating environment.
