Active high-side switch with integrated protection
The Infineon BSP742TXUMA1 is a single-channel N-channel high-side power switch from the miniPROFET® family, designed for general-purpose on/off switching of resistive, inductive, and capacitive loads. It integrates current limiting, over-temperature, and over-voltage fault protection, making it suitable for rugged 12V and 24V automotive and industrial environments where a simple On/Off interface is sufficient. The 260 mOhm typical Rds(on) keeps conduction losses manageable for loads up to 800 mA continuous.
Load voltage range and thermal capability
Rated for a load supply from 5 V to 34 V, the BSP742TXUMA1 covers 5 V logic rails, 12 V automotive battery lines, and 24 V industrial bus voltages without needing an external Vcc supply — the device is self-powered from the load pin.
No external Vcc pin simplifies the layout — the switch is driven directly by a logic-level On/Off signal on the input pin.
