Product details

Four-channel PROFET with 45 mOhm Rds(on) — what it drives

The Infineon BTS5434GXUMA1 is a four-channel high-side power switch from the PROFET family, rated 3.4 A continuous per output with a typical on-resistance of 45 mOhm.

Fault coverage and diagnostic feedback

The parallel interface with non-inverting input and N-channel output configuration means each channel turns on when the logic pin goes high, no external Vcc supply required for the control logic. Auto-restart feature re-enables the channel after a fault condition clears, reducing maintenance intervention in remote equipment.

Infineon lists the BTS5434GXUMA1 as obsolete. For BOM continuity, the closest functional peer within the same family is the BTS5434G — verify pin compatibility and thermal pad footprint before substituting, as the 28-SOIC land pattern may differ between suffix variants.

Frequently asked questions

Is the BTS5434GXUMA1 obsolete?

Yes, Infineon lists the BTS5434GXUMA1 as obsolete. No official drop-in replacement has been assigned. The BTS5434G is the same base part number and shares the same 28-SOIC package and 4-channel high-side topology, but you should verify pinout and thermal performance against your specific board layout before committing.
