Product details

Dual high-side switch — 19 mOhm, 5.5 A per channel

The BTS52422LAUMA1 is an Infineon PROFET dual-channel high-side power switch rated for 5.5 A continuous output per channel with a typical on-resistance of 19 mOhm. The output stage is N-channel with a 1:1 input-to-output ratio, driven by a non-inverting On/Off interface. Auto-restart and a status flag output are integrated for system-level diagnostics.

Protection set — fixed current limit, open-load, over-temp, over-voltage

These are hardwired thresholds — no external programming — which simplifies the BOM but means the current limit is a fixed value, not adjustable per load. The open-load detect flags a disconnected output when the switch is off, useful for lamp-out or actuator-disconnect diagnostics.

For BOM lines still specifying this device, sourcing runs through independent distribution on a last-time-buy or surplus basis.

Frequently asked questions

What is the replacement for BTS52422LAUMA1?

A pin-compatible replacement within the PROFET family is not confirmed — verify the pinout and protection features against any candidate alternative before substituting into an existing board layout.
