Infineon BTS428L2 Series Power Switch IC, 75W Power Rating, 5.8A Operating Current - BTS428L2ATMA1


This power switch IC is a high‑side semiconductor device designed for automotive electrical systems, providing controlled switching of multiple loads from a single input. It is intended for surface‑mounted use in applications requiring coordinated on/off control and protection features within vehicle environments.

Features and Benefits:


• Five outputs for multiplexed load control and simplified wiring
• Supports a maximum supply voltage of 41V enabling robust transient tolerance
• Operates from 4.75V supply for compatibility with typical vehicle rails
• Rds(on) of 120 mΩ to reduce conduction losses and heat generation
• 5.8A operating current to drive moderate automotive loads reliably
• Power rating of 75W to handle aggregated channel dissipation

Applications


• Suitable for centralised body control module implementations
• Ideal for switching lighting and auxiliary systems in vehicles
• Used with electronic control units requiring multiple outputs
• Can be used for fan and pump actuation in automotive systems
• Suited to compact surface‑mount assemblies on vehicle PCBs

What thermal range can be expected during vehicle operation?


The device is specified to function between -40 °C and 150 °C ambient, allowing use across cold starts and high‑temperature engine‑bay conditions.

How many control inputs are required to operate the outputs?


A single input controls the device, providing coordinated drive across its five outputs for simplified command interfaces.

What package and mounting style does this component use?


It is supplied in a TO‑252 package designed for surface‑mount installation to save board area.

How does the device topology affect system design?


As a high‑side switch, it connects loads to the positive supply, simplifying ground‑referenced sensors and load wiring and easing integration with typical automotive supply architectures.
