A much cheaper option then the high side switch, but one time use only.\nPopulate with a  appropriate 1206 fast blow fuse.\nExample: Fuse Fast Blow 10A 1206 MCCFB1206TFF/10

The Infineon BTS50055-1TMC is a highside high current power switch with buildt in reverse\npolarity and temperature protection.\nIt's also used to measure current consumption; Current_Feedback as analog output.\nTo enable the high power switch Enable_Vin_fused must be driven low.\nBoth Current_Feedback and Enable_Vin_fused goes to the MCU so it can act on over current\nand act as a breaker.
