Each of the two N-channel outputs is rated for a maximum continuous current of 1.8A, with a typical on-resistance of 140mOhm (max) per channel. The switch operates from a 4.5V to 28V load supply and requires no Vcc/Vdd bias — the load voltage itself powers the internal charge pump and logic. Input is non-inverting with a simple On/Off interface, making it a drop-in replacement for a discrete MOSFET plus driver in applications where fault reporting and protection are needed. ## Fault protection suite — what it covers The BTS5231GS integrates current limiting (fixed), open-load detection, overtemperature shutdown, and overvoltage clamping. The Status Flag output signals a fault condition to the microcontroller, and the Auto Restart feature re-enables the channel after an overtemperature fault once the junction cools below the threshold. This protection set eliminates the need for external sense resistors, comparators, or a separate overvoltage clamp diode — the PROFET handles it on-chip. For a 24V truck system or a 12V passenger-car ECU, the 28V load supply maximum provides headroom for load-dump transients, though the overvoltage clamp catches the spike if it exceeds the rating. ## 150°C junction — where it fits The 150°C Tj ceiling means the die can handle self-heating from a 1.8A load in a 105°C ambient, provided the PCB copper area under the PG-DSO-14-18 package is adequate for heat spreading. ## Obsolete — sourcing reality Infineon lists the BTS5231GS as Obsolete. For existing BOM lines, procurement must turn to the independent distribution channel — surplus inventory, last-time-buy stockpiles, or broker-sourced material. No pin-compatible second source or direct replacement is listed in the Infineon PROFET family with the same PG-DSO-14-18 footprint and dual 1.8A rating. A board redesign with a current-generation PROFET (e.g., BTS5xxx series in a similar package) is the typical migration path, but the pinout and protection feature set must be verified against the new datasheet.","metaTitle":"BTS5231GS PROFET dual high-side switch, 1.8A, obsolete","metaDescription":"Infineon BTS5231GS PROFET dual high-side power switch, 1.8A max per channel, 140mOhm Rds(on), -40 to 150°C junction.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Infineon Technologies","Series":"PROFET®","Package":"Tape & Reel (TR)","Features":"Auto Restart, Status Flag","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"140mOhm (Max)","Mounting Type":"Surface Mount","Package / Case":"14-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Obsolete","Voltage - Load":"4.5V ~ 28V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Open Load Detect, Over Temperature, Over Voltage","Number of Outputs":"2","Base Product Number":"BTS5231","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C ~ 150°C (TJ)","Current - Output (Max)":"1.8A","Supplier Device Package":"PG-DSO-14-18","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8f611b1ad401ba9153b7ee7ac26ab520.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for BTS5231GS?","answer":"Infineon has not published a direct pin-compatible successor for the BTS5231GS.
