• Fan and pump motor drives

Procurement Notes

Verify the specific suffix ATMA1 to confirm the exact tape-and-reel packaging configuration required for automated assembly processes. Ensure that the procurement channel sources components directly from authorized distributors or the manufacturer to guarantee authenticity and traceability. Confirm RoHS compliance status and check for any regional sales restrictions or obsolescence notices prior to finalizing orders.

Selection Notes

Select this component when a single-channel high-side switch with a 33 A continuous rating is required. The low 3 mOhm on-resistance makes it suitable for high-current applications where minimizing conduction losses is critical. Ensure the system voltage remains within the 8 V to 18 V operating range and that the thermal design can handle the specified power dissipation in the TO-263-7 package.

Part Context

This part belongs to the Power PROFET family of smart high-side switches designed for automotive environments. It integrates N-channel MOSFET technology with control logic and protection circuits. The device simplifies circuit design by replacing discrete components with a single integrated solution, offering robust performance and reliability for demanding power distribution tasks.

Replacement Considerations

Check for direct substitutes within the BTS50015 series, such as the BTS500151TAAATMA1, ensuring pin compatibility and electrical parameter alignment. Verify that any alternative part meets the same automotive qualification standards and package dimensions to maintain board layout integrity.
