The reset timeout is 140 ms minimum, giving the power supplies and oscillator time to stabilise before the processor is released from reset. ## Thresholds and the adjustable rail The adjustable input (SENSE3) lets you monitor a third rail at any voltage above the internal reference — a common use case is a 1.2 V core supply or a 5 V I/O rail. The resistor divider ratio sets the trip point, so the BOM adds two resistors but gains flexibility. The fixed thresholds are factory-trimmed for 1.8 V and 3.3 V systems, which covers the most common mixed-voltage logic pairs in industrial designs. It suits factory automation, outdoor telecom cabinets, motor drives, and power-supply control boards — any environment where the board sees seasonal temperature swings but not engine-bay heat.","metaTitle":"TPS3307-18DRG4 Multi-Voltage Supervisor, 3 Rails, Active","metaDescription":"Texas Instruments TPS3307-18DRG4 multi-voltage supervisor monitors three rails: 1.68V, 2.93V, and adjustable.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Type":"Multi-Voltage Supervisor","Reset":"Active High/Active Low","Output":"Push-Pull, Totem Pole","Series":"-","Package":"Tape & Reel (TR)","Mounting Type":"Surface Mount","Reset Timeout":"140ms Minimum","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Base Product Number":"TPS3307","Voltage - Threshold":"1.68V, 2.93V, Adj","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"8-SOIC","Number of Voltages Monitored":"3"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.3000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8827b21deee1fba8c815128819be5cd7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3307-18DRG4/alternatives.json"},"ai":{"faq":[{"question":"What are the exact threshold voltages for TPS3307-18DRG4?","answer":"The three monitored thresholds are 1.68 V (for a 1.8 V rail), 2.93 V (for a 3.3 V rail), and an adjustable input that lets you set the third threshold with an external resistor divider."},{"question":"Is TPS3307-18DRG4 a direct replacement for TPS3307-18DR?","answer":"The TPS3307-18DRG4 is functionally identical to the TPS3307-18DR — same thresholds, same reset timeout, same package.
