Product details

SPOC SPI power controller for automotive power distribution

The Infineon BTS54040LBFXUMA1 is a SPOC (Smart Power Controller) with an SPI interface, designed for high-side switching in automotive and industrial power distribution systems. Its SPI communication enables diagnostic feedback and flexible load control, making it suitable for fuse-replacement and intelligent power management in body controllers, junction boxes, and ECU power rails.

Bulk package — verify handling for automated assembly

This part is, not Tape & Reel. For high-volume pick-and-place lines, confirm feeder compatibility or request a reeled variant. Bulk is common for engineering samples or low-volume builds but may require manual loading for automated placement.

For volume commitments or scheduled releases, we can support blanket orders with fixed pricing windows.

Frequently asked questions

Where can I buy BTS54040LBFXUMA1?

The BTS54040LBFXUMA1 is available to order against an RFQ through independent distribution. Submit a request for current pricing and availability.

What is the replacement for BTS54040LBFXUMA1?

No official replacement is listed. The BTS54040LBFXUMA1 is still active, so no substitution is needed. For a simpler on/off high-side switch without SPI, consider the BTS142DATMA1 (HITFET, 23 mOhm, 42 V load, single-channel low-side), but verify pin compatibility and control interface differences.
