Dual 40 mOhm high-side switch — what it drives and where it sits
The Infineon BTS52362GSXUMA1 is a dual-channel high-side power switch from the PROFET family, designed to drive resistive, inductive, and capacitive loads in automotive and industrial systems. Each of the two N-channel outputs delivers up to 3.2 A continuous with a typical on-resistance of 40 mOhm, keeping conduction losses low in a 14-SOIC footprint. The 1:1 input-to-output ratio means each of the two On/Off control pins independently switches one output, so the part can drive two separate loads — lamps, solenoids, relays, or small motors — without external logic.
40 mOhm Rds(on) at 3.2 A — thermal budget and load matching
With a typical 40 mOhm Rds(on) and a 3.2 A maximum output per channel, the conduction loss at full load is roughly 0.4 W per channel. That number sets the copper area needed on the PCB to keep the junction below the 150 °C maximum operating temperature — a solid ground-plane pour under the PG-DSO-14-32 package is expected. The switch handles a load voltage range of 4.5 V to 28 V, covering nominal 5 V, 12 V, and 24 V rails. The built-in fault protection — current limiting, open load detection, over-temperature, and over-voltage — means the microcontroller side only needs a non-inverting logic signal to command the switch.
Obsolete — last-time-buy window is closed
Infineon has marked the BTS52362GSXUMA1 as obsolete. The last-time-buy window has passed, so new production orders through the factory channel are no longer accepted. Any available stock is what remains in the independent distribution channel — date codes and provenance must be verified before committing to a BOM line. No official successor part is listed by Infineon for this specific order code. Buyers needing a drop-in replacement should cross-reference the BTS5236 base product number against other PROFET variants in the same 14-SOIC PG-DSO-14-32 package, but pin compatibility is not guaranteed without a datasheet comparison.
Package and footprint — 14-SOIC with Infineon PG-DSO-14-32
The 1.27 mm pitch SOIC footprint is standard, but the thermal pad dimensions and exposed die attach pad (if present) should be confirmed against the Infineon package drawing for that specific variant. The Auto Restart feature and Status Flag output are useful for systems that need to recover from a fault without a power cycle.
