It integrates an N-channel MOSFET with a typical on-resistance of 800 mOhm and a maximum load voltage rating of 60V, giving headroom for load-dump transients on a nominal 12V rail. ## Thermal and protection envelope The fault protection block includes over-temperature and over-voltage shutdown, and the Auto Restart feature re-enables the output after a thermal fault cools, reducing the need for external watchdog circuitry. ## Package and supply simplicity The device comes in a PG-SOT223-4 surface-mount package (TO-261-4 equivalent), a four-pin footprint with a large drain tab for heat sinking into the PCB copper plane. No external Vcc supply is required — the switch is self-powered from the load voltage, so the interface is a single On/Off logic input controlling the output with a 1:1 ratio.","metaTitle":"Infineon BTS41K0SMENHUMA1 Automotive High-Side Switch","metaDescription":"Infineon BTS41K0SMENHUMA1 automotive high-side power switch, 800 mOhm Rds(on), 60V load, -40°C to 150°C.
