Product details

The Infineon BTS4300SGAXUMA1 is a single-channel N-channel high-side power distribution switch in a PG-DSO-8-24 package. It switches a load from 5 V up to 34 V, with a typical on-resistance of 300 mOhm and a maximum continuous output current of 400 mA. The On/Off interface accepts a non-inverting logic signal to gate the output, and the Status Flag pin reports fault conditions back to the controller.

Package and field-swap reality

The part comes in a PG-DSO-8-24 package (3.90 mm width). If you are doing a field repair, you can swap this on site without hot air, as long as you have the SOIC-8 footprint on the board. No lab bench needed.

For BOM planning, this is a stable line item — no near-term LTB risk.

Frequently asked questions

Does BTS4300SGAXUMA1 include short circuit protection?

Yes, it includes fixed current limiting, which protects against short circuits by holding the output current to a safe level.

Does BTS4300SGAXUMA1 have over temperature protection?

Yes, it includes over-temperature shutdown that turns off the switch if the die temperature exceeds the threshold.
