PROFET high-side switch — 190 mOhm, 1.8 A, automotive grade
The Infineon BTS410E2E3062ANTMA1 is a single-channel PROFET high-side power switch in a PG-TO263-5-2 (D²Pak) surface-mount package. It switches a resistive or inductive load on the high side with a typical on-resistance of 190 mOhm, rated for a continuous output current of 1.8 A. The load supply range spans 4.7 V to 42 V, covering 12 V and 24 V automotive systems with margin for load-dump transients.
On-resistance and thermal budget
The 190 mOhm typical Rds(on) at 25°C sets the conduction loss floor.
Fault protection and diagnostics
Integrated fault protection covers current limiting (fixed), open-load detection, over-temperature, over-voltage, and undervoltage lockout. The auto-restart feature re-enables the output after a fault clears, which suits unmonitored loads like lamps or solenoids. The input is non-inverting with a simple On/Off interface — no Vcc supply pin is needed, so the switch is self-powered from the load supply.
