Smart Highside Power Switch For Industrial Applications

The highly integrated profet family protected fet incorporates a broad range of smart features like diagnose and protection.

Smart highside power switch for industrial applications.

The device enlarges st s family of galvanic isolated high side switches. 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. The galvanic isolated octal high side smart power switch enhances diagnostics and system management by providing a 20 mhz spi port allowing both per channel over temperature signalization and efficient daisy chaining of multiple devices. Smart sense high side power switch for industrial applications features.

The vast range of smart features makes profet high side switches ideal for a variety of automotive and industrial applications. 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. Infineon technologies bts50025 1tad smart high side power switch is designed to drive high current loads up to 60a. The profet family of devices is also capable of protecting against dynamic overvoltage such as load dump and inductive load turn off.

Due to their outstanding energy robustness they are perfectly suitable for switching even higher inductive loads and driving relays. Profet intelligent power high side switches consist of a dmos power transistor and cmos logic circuitry for complete built in protection. 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. Application µc compatible power switch with diagnostic feedback for 12 v and 24 v dc grounded loads in industrial applications all types of resistive inductive and capacitive loads.

Smart high side power switch for industrial applications one channel. µc compatible power switch for 12 v and 24 v dc industrial applications replaces electromechanical relays and discrete circuits general description n channel vertical power fet with charge pump ground referenced cmos compatible input monolithically integrated in smart sipmos technology. The high current loads are ideal for automotive applications such as switched battery couplings power distribution switches heaters and glow plugs. A power good output indicates the status of the process side power supply.

Freescale s intelligent high side switches are designed to control a wide variety of loads in automotive and industrial systems.
