Product details

Dual high-side switch for 12V automotive and industrial loads

The Infineon BTS50202EKAXUMA2 is a dual-channel high-side power switch from the PROFET family, designed to drive resistive, inductive, and capacitive loads in 12V automotive body electronics and industrial control systems. Each N-channel output delivers up to 5A continuous with a typical on-resistance of 40 mOhm, minimising conduction losses in the power path. The switch operates from an 8V to 18V load supply and requires no external Vcc bias — the gate drive is self-supplied from the load rail. Input logic is non-inverting, with a simple On/Off interface that directly accepts microcontroller GPIO levels.

At 5A load, the 40 mOhm typical Rds(on) produces about 1W of dissipation per channel.

Built-in fault protection reduces external BOM

These protections eliminate the need for external sense resistors, comparators, or TVS diodes in many 12V load-switching applications. The Auto Restart feature re-enables the output after a fault condition clears, which is useful for transient overloads like lamp inrush or motor stall.

Frequently asked questions

Does BTS50202EKAXUMA2 have overcurrent protection?

Yes. The BTS50202 includes fixed current limiting as part of its fault protection set, along with open-load detection, over-temperature shutdown, and over-voltage clamping.

What is the Rds(on) of BTS50202EKAXUMA2?

The typical Rds(on) is 40 mOhm per channel at 25°C junction temperature. Actual on-resistance increases with temperature per the normalised curve in the datasheet.
