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
Built-in fault protection covers current limiting (fixed threshold), open-load detection, over-temperature shutdown, and over-voltage clamping — the open-load detect is useful for wiring integrity checks in automotive body controllers or industrial I/O modules where a disconnected actuator must be flagged. 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.
Obsolete — sourcing and replacement path
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.
