Dual high-side switch with 45 mOhm Rds(on) and 3.3 A per channel
The BTS5234GXUMA1 is a dual-channel high-side power switch from Infineon's PROFET® family, designed for general-purpose switched loads in automotive and industrial environments. Each of the two N-channel outputs delivers up to 3.3 A continuous, with a typical on-resistance of 45 mOhm that keeps conduction losses manageable at full load.
Fault protection and temperature range for harsh environments
Integrated fault protection covers current limiting (fixed), open-load detection, over-temperature shutdown, and over-voltage clamping — the switch handles the common failure modes in a 12 V or 24 V truck/automotive system without external clamp diodes. The Auto Restart feature re-enables the output after a thermal fault once the die cools, reducing nuisance trips in intermittent overloads.
Obsolete — sourcing via surplus and broker channels
Infineon lists the BTS5234GXUMA1 as obsolete. For existing BOM lines that require this exact order code, procurement must turn to independent distribution and surplus stock — sealed reels with consistent date-codes are the preferred source to avoid repackaged or mixed-lot material.
PG-DSO-20-21 package and surface-mount footprint
The switch is housed in a 20-SOIC wide-body package (0.295-inch body width, 7.50 mm) with the Infineon PG-DSO-20-21 pinout. Surface-mount assembly requires a standard SOIC-20 wide footprint — the exposed pad on the underside (if present on this variant) aids thermal conduction to the PCB copper plane.
