190 mOhm Rds(on) — sizing the load budget
The BTS410F2 E3043: The BTS410F2 is a single-channel PROFET high-side power switch from Infineon. Its 190 mOhm typical Rds(on) at 1.6 A max output sets the conduction loss floor.
The load supply range spans 4.7 V to 42 V. No external Vcc supply is needed — the switch is self-powered from the load rail.
Fault protection set — why you pick a smart switch over a bare MOSFET
Integrated protection includes fixed current limiting, open-load detection, over-temperature shutdown, and over-voltage clamping. The auto-restart feature re-enables the output after a fault clears, which is useful for driving lamps or solenoids that present a cold-start inrush.
Temperature grade and package — where it fits physically
The TO-220-5 through-hole package (P-TO220-5) provides a direct thermal path to a heatsink or chassis ground plane.
Obsolete — planning the BOM transition
Infineon lists the BTS410F2 as obsolete. For new designs or long-term production, a pin-compatible PROFET replacement should be qualified against the load current and protection requirements.
