Product details

High-side switch for 12V/24V loads

The Infineon BTS441TGATMA1 is a single-channel PROFET high-side power switch designed to drive resistive, inductive, and lamp loads in 12V and 24V automotive and industrial systems. It switches up to 17A continuous from a 4.75V to 43V supply rail, with a typical on-resistance of 15mOhm — low enough to keep conduction losses manageable in a TO-263-5 D²Pak footprint.

Built-in fault protection

The switch integrates current limiting (fixed threshold), over-temperature shutdown, and over-voltage clamping — so a shorted load or a stalled motor won't take out the IC or the rest of the board. The protection latches off under fault and requires a power cycle or a logic toggle to reset, which matches the typical behaviour of a PROFET in a safety-critical rail.
