Housed in a SOT-23-3 package (also known as TO-236-3 or SC-59), the three-pin footprint — VDD, GND, and RESET — routes directly to the microcontroller's supply and reset input with no external components beyond a decoupling cap.","metaTitle":"LM809M3X-4.00/NOPB Texas Instruments Supervisor","metaDescription":"Texas Instruments LM809M3X-4.00/NOPB simple reset/power-on reset IC, active-low push-pull output, 4V threshold, 140ms timeout, SOT-23-3, -40°C to 105°C.","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":"Bulk","Mounting Type":"Surface Mount","Reset Timeout":"140ms Minimum","Package / Case":"TO-236-3, SC-59, SOT-23-3","lifecycle_stage":"eol_hot","Voltage - Threshold":"4V","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"SOT-23-3","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.29","stockQuantity":0,"priceTiers":[{"qty":1031,"price":"$0.29000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4e3ddd1a85c798a5bed07dff1ceed070.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is LM809M3X-4.00/NOPB's reset polarity and output type?","answer":"It has an active-low reset output with a push-pull, totem-pole stage, so it drives the reset line high or low without an external pull-up resistor."},{"question":"Will LM809M3X-4.00/NOPB drop into a board designed for TL7702BID without rewiring?","answer":"No — the TL7702BID has an open-drain output and supports both active-high and active-low resets with a 270 ns typical propagation delay, while the LM809M3X-4.00/NOPB is push-pull, active-low only, with a 140 ms timeout.
