Infineon lists the BTS5441G as obsolete. No official successor is recorded on this line — the closest functional match would be a current PROFET 2G+ or PROFET+ 28 V device, but pin compatibility and footprint must be verified against the original board layout.
4-channel high-side switch — 19 mOhm and 5.6 A per output
The BTS5441G is a four-output high-side power switch from Infineon's PROFET family, built with an N-channel MOSFET per channel. Each output is rated for a continuous 5.6 A maximum, with a typical on-resistance of 19 mOhm. The 4.5 V to 28 V load supply range covers standard automotive and industrial 12 V and 24 V rails. Protection features include current limiting (fixed), open-load detection, over-temperature shutdown, and over-voltage clamping — all integrated, so no external sense resistors or clamp diodes are needed. The 1:1 input-to-output ratio and non-inverting input type mean a logic-high on the control pin turns the corresponding output on.
Package and temperature — PG-DSO-28, 150°C junction
The junction temperature range extends to 150°C, which suits under-hood automotive or industrial enclosures where ambient heat is high. No external Vcc supply is needed — the switch is self-powered from the load rail.
