The reset output is Active Low, open-drain, so it can be wire-ORed with other reset sources on the same pull-up rail — common in multi-rail systems where a single fault pulls the whole system into reset. ## 125°C junction – industrial and automotive margin The reset timeout is adjustable/selectable, letting the designer match the power-up settling time of the downstream load — a 100 ms timeout might work for a flash-based MCU, but a larger FPGA may need a longer delay programmed via an external capacitor. ## 10-VSON (3x3) – footprint and thermal pad Texas Instruments is the sole manufacturer.","metaTitle":"TPS3850G12DRCT – 1.2V Threshold Supervisor, Active Low","metaDescription":"Texas Instruments TPS3850G12DRCT – Simple Reset/Power-On Reset, 1.2V threshold, Active Low open-drain output. -40°C to 125°C, 10-VSON (3x3) package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Open Drain or Open Collector","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"Adjustable/Selectable","Package / Case":"10-VFDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3850","Voltage - Threshold":"1.2V","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"10-VSON (3x3)","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.0000","priceTiers":[{"qty":1,"price":"$3.00000","currency":"USD"},{"qty":10,"price":"$2.69400","currency":"USD"},{"qty":25,"price":"$2.54120","currency":"USD"},{"qty":100,"price":"$2.16520","currency":"USD"},{"qty":250,"price":"$1.82956","currency":"USD"},{"qty":500,"price":"$1.60086","currency":"USD"},{"qty":1250,"price":"$1.32643","currency":"USD"},{"qty":2500,"price":"$1.29450","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/bc290ea6dc9188b1fefd6210f8765b60.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3850G12DRCT/alternatives.json"},"ai":{"faq":[{"question":"Is TPS3850G12DRCT active high or active low?","answer":"Active Low.
