Infineon BTS4300SGAXUMA1 High Side 1, High Side Power Switch Power Switch IC 8-Pin, DSO

This power switch IC is a compact high-side device designed for automotive load management, providing controlled switching of multiple circuits from a single control input. It is intended for vehicle electronics where robust high-side switching is required and operates across a broad supply range suitable for typical automotive systems. The device is supplied in a surface-mount DSO package and is configured to manage several outputs under constrained power conditions, offering a balance of functionality and space-efficient mounting.

• 34V maximum supply voltage enables wide automotive voltage tolerance
• 0.4A operating current supports moderate load switching
• 600mΩ Rds(on) delivers reduced conduction losses during operation
• 0.8W power rating manages continuous dissipation in compact systems
• -40°C to 150°C operating range maintains performance across climates
• Five outputs controlled from a single input simplifies wiring

• Suitable for distributed automotive auxiliary load switching
• Ideal for body control modules requiring several switched lines
• Used with sensor arrays needing centralised power control
• Can be used for compact multi-channel power distribution boards
• Useful in systems requiring surface-mount high-side switching

A single input drives all five outputs, enabling centralised control of multiple loads without separate drive signals for each channel.

The surface-mount DSO 8-pin package requires land pattern design for reliable solder joints and thermal conduction

With a 0.8W power rating the device needs appropriate copper area or thermal vias to spread heat and keep junction temperatures within limits at higher ambient temperatures.

The component conforms to automotive AEC standards, making it suitable for in-vehicle applications that follow those industry criteria.
