Product details

15 mOhm high-side switch for 12V and 24V loads

The Infineon BTS441TAKSA1 is a single-channel PROFET high-side power switch rated for 17 A continuous output with a typical on-resistance of 15 mOhm.

Built-in fault protection for rugged environments

This switch integrates current limiting (fixed), over-temperature shutdown, and over-voltage clamping, so it survives shorted loads and supply transients without external clamp diodes. It is a non-inverting, high-side driver that requires no Vcc supply pin — the load voltage itself powers the internal charge pump, simplifying the BOM.

The BTS441TAKSA1 is listed as obsolete.
