It integrates an N-channel power MOSFET with a 250 mOhm typical Rds(on) and delivers up to 400 mA continuous output. The switch operates from a 5V to 34V load supply, covering 12V and 24V nominal rails with headroom for load-dump transients. Input is non-inverting with a simple On/Off interface; no external Vcc supply is needed — the gate drive is self-supplied from the load voltage. ## Fault protection set for robust operation Built-in fault protection covers current limiting (fixed), open load detection, overtemperature shutdown, and overvoltage clamping. The overtemperature protection is a key feature for high-ambient or stalled-load conditions — the die shuts off before junction damage, then auto-restarts when it cools. Open load detection flags a disconnected harness, useful for lamp-out or solenoid-integrity diagnostics. The fixed current limit prevents excessive inrush during capacitive or cold-filament turn-on. ## Temperature grade and package Thermal dissipation is limited by the small copper area — at 400 mA continuous, the 250 mOhm Rds(on) dissipates 40 mW, but derating is needed if ambient exceeds 105°C or if the PCB lacks adequate copper pour. The package is ROHS3 compliant.","metaTitle":"Infineon BSP742RXUMA1 miniPROFET High-Side Switch, 250mOhm","metaDescription":"Infineon BSP742RXUMA1 miniPROFET high-side power switch. 250mOhm Rds(on), 400mA output, 5-34V load, -40°C to 150°C junction.
