Providing embedded protective functions.

Smart highside power switch for industrial applications. The device enlarges st s family of galvanic isolated high side switches. The vast range of smart features makes profet high side switches ideal for a variety of automotive and industrial applications. A power good output indicates the status of the process side power supply. Smart high side power switch for industrial applications one channel.

Infineon technologies bts50025 1tad smart high side power switch is designed to drive high current loads up to 60a. The highly integrated profet family protected fet incorporates a broad range of smart features like diagnose and protection. The well established high side switch industrial profet products were designed for targeting a variety of industrial applications which include all types of resistive inductive and capacitive loads. The profet family of devices is also capable of protecting against dynamic overvoltage such as load dump and inductive load turn off.

This presentation describes freescale s high side switch portfolio and roadmap device features considerations for their use potential applications and available design and support tools. The high current loads are ideal for automotive applications such as switched battery couplings power distribution switches heaters and glow plugs. Freescale s intelligent high side switches are designed to control a wide variety of loads in automotive and industrial systems. With adjustable current limit high accuracy current sense and a wide range of rdsons our smart high side switches provide the optimal solution for your specific use case.

Profet intelligent power high side switches consist of a dmos power transistor and cmos logic circuitry for complete built in protection. Due to their outstanding energy robustness they are perfectly suitable for switching even higher inductive loads and driving relays. Smart sense high side power switch for industrial applications features. 1 x 1 ω features current controlled input short circuit protection current limitation overload protection overvoltage protection including load dump switching inductive loads clamp of negative voltage at output with inductive loads.
