Product Description
Infineon BTS428L2ATMA1 high side power switch IC is a 5-pin surface-mount semiconductor device designed to provide controlled switching of multiple automotive loads from a single input. Featuring a TO-252 package type, it supports a maximum supply voltage of 41V, minimum supply voltage of 4.75V, and a power rating of 75W, enabling the switch to handle significant loads while maintaining thermal and electrical robustness.
This device offers a low switch on resistance (Rds(on)) of 120mΩ which reduces conduction losses and heat generation, ensuring efficient operation. It supports a continuous operating current of 5.8A, which is ideal for driving moderate loads like lighting, auxiliary systems, fans, and pumps typically found in automotive environments.
The device operates reliably over a wide ambient temperature range from -40°C to 150°C, making it suitable for the extreme conditions encountered in engine bays and cold start scenarios. Its single input controls all five outputs, simplifying multiplexed load management and reducing wiring complexity in vehicle body control modules and electronic control units.
The TO-252 package allows for compact surface-mount assembly on vehicle PCBs, optimizing space while providing robust electrical performance. This high side switch topology connects loads to the positive supply, simplifying integration with ground-referenced sensors and load wiring.
Applications include centralized body control, lighting control, auxiliary automotive systems, and control of fans and pumps. This component complies with the Automotive Electronics Council (AEC) standard, ensuring automotive-grade reliability.
Supports multiplexed control of five outputs from a single input. Operates with supply voltage from 4.75 V up to 41 V. Low on resistance of 120 mΩ reduces loss and temperature rise. Power dissipation rating of 75 W for reliable operation under load.
Wide operating temperature range from -40 °C to 150 °C. Compact 5-pin TO-252 package for surface mounting. Designed for automotive applications including lighting and auxiliary loads. Single input simplifies system design and wiring complexity.
