That threshold sits between the common 2.5V and 3.0V supervisor trip points — it's designed for a 3.3V rail that needs to hold above 2.7V to keep downstream logic from corrupting state, but can tolerate a dip to 2.5V before the processor browns out. For a 3.3V MCU with a 2.7V minimum operating voltage, this supervisor gives about 75mV of noise margin before the reset fires. The reset timeout is 140ms minimum — long enough to let the main supply rail settle after power-up, but short enough that a 3.3V rail with a 10µF output cap and a 1A load step won't keep the system in reset long enough to miss a real-time event. The push-pull output drives the reset line high or low without an external pull-up resistor, saving a component and one PCB trace. ## Active lifecycle — no end-of-life risk for this BOM line The 8-SOIC package is a standard footprint with 1.27mm pin pitch, easy to route on a two-layer board and compatible with common reflow profiles. No stock-holding claim — each order is validated against the manufacturer's active inventory and lead time before commitment.","metaTitle":"STM806RM6F Simple Reset IC, 2.625V Threshold, 8-SOIC","metaDescription":"STMicroelectronics STM806RM6F simple reset/power-on reset IC, active-low push-pull output, 2.625V threshold, 140ms timeout, -40 to 85°C, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Push-Pull, Totem Pole","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"140ms Minimum","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Threshold":"2.625V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-SOIC","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.65","priceTiers":[{"qty":1,"price":"$3.65000","currency":"USD"},{"qty":10,"price":"$3.27900","currency":"USD"},{"qty":25,"price":"$3.09960","currency":"USD"},{"qty":100,"price":"$2.68650","currency":"USD"},{"qty":250,"price":"$2.54872","currency":"USD"},{"qty":500,"price":"$2.28696","currency":"USD"},{"qty":1000,"price":"$2.27448","currency":"USD"},{"qty":2500,"price":"$2.27448","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/13c3ef00103aab18295f01fe57716cda.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM806RM6F/alternatives.json"},"ai":{"faq":[{"question":"Will STM806RM6F drop into a board designed for STM809LWX6F?","answer":"The STM806RM6F and STM809LWX6F share the same package (8-SOIC), same reset type (Active Low), same output (Push-Pull, Totem Pole), and same 140ms reset timeout. The key difference is the voltage threshold: STM806RM6F trips at 2.625V, while STM809LWX6F trips at a different level. If the board's supply rail and supervisor threshold match 2.625V, the STM806RM6F is a drop-in replacement without rewiring. Verify the threshold on your BOM before swapping."},{"question":"What compliance documentation does STMicroelectronics provide for STM806RM6F?","answer":"The STM806RM6F is RoHS3 compliant, meeting EU Directive 2011/65/EU and its amendments.
