Each channel is controlled by a non-inverting On/Off logic input in a 1:1 ratio, so one logic pin drives one output with no address decoding. The output configuration is low-side (N-channel open-drain), meaning the load connects between the supply rail and the switch drain, and the switch sinks current to ground when activated. ## Fault coverage for harsh environments The BTS3408G integrates fixed current limiting, open-load detection, over-temperature shutdown, and over-voltage clamping. These protections let the switch survive a shorted load or a stalled motor without external clamp diodes or sense resistors — the part handles the fault and reports it via the Status Flag output. The 8-SOIC package (PG-DSO-8-36 footprint) keeps the board area small, but the 480 mOhm Rds(on) at 550 mA produces about 145 mW per channel — thermal vias under the package are recommended for continuous full-load operation at the high end of the temperature range. ## Obsolete — sourcing through independent distribution The BTS3408G carries an Obsolete product status. Because this is a mature, discontinued device, date-code consistency across a production batch may vary. Buyers should confirm the date-code range and test compatibility with any downstream qualification requirements (e.g., AEC-Q grade, moisture-sensitivity level) before committing the reel to the line.","metaTitle":"BTS3408G HITFET dual low-side switch, 480 mOhm, 550 mA","metaDescription":"Infineon BTS3408G HITFET dual N-channel low-side switch, 480 mOhm Rds(on), 550 mA per channel, 4.5-60 V load.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Infineon Technologies","Series":"HITFET®","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)":"480mOhm","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Obsolete","Voltage - Load":"4.5V ~ 60V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Open Load Detect, Over Temperature, Over Voltage","Number of Outputs":"2","Base Product Number":"BTS3408","Output Configuration":"Low Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C ~ 150°C (TJ)","Current - Output (Max)":"550mA","Supplier Device Package":"PG-DSO-8-36","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4f88023a283a9c50f7d60bbfadf53f03.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BTS3408G","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BTS3408G when reusing this data.
