This reset timeout is long enough to let a typical MCU or FPGA complete its internal power-up sequence before the processor sees the release edge. The open-drain output lets you wire-OR the reset signal with other supervisors or a manual reset button, pulling the line low when any fault occurs. ## 125°C junction — under-hood or furnace-side The 8-SON package's exposed pad helps keep the die temperature within spec when the supervisor is powered from a 5V rail that may see ripple. Compared to the TLV803EA29VDBZR, which has a 130ms minimum reset timeout and a 1V supply range, the TPS3851G50EDRBT is fixed at 5V threshold with a longer 170ms timeout — a better fit for 5V-only systems where the processor needs more time to stabilise before the reset releases. No end-of-life notice or last-time-buy date has been issued. Sourcing is per RFQ — we confirm current availability and pricing at quote time. The base product number TPS3851 covers the family; the G50EDRBT suffix locks the 5V threshold, active-low output, and 8-SON package.","metaTitle":"TPS3851G50EDRBT – TI Simple Reset/Power-On Reset, Active Low","metaDescription":"TPS3851G50EDRBT from Texas Instruments: Simple Reset/Power-On Reset IC, Active Low output, 5V threshold, 170ms min reset timeout, -40°C to 125°C, 8-SON 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":"170ms Minimum","Package / Case":"8-VDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3851","Voltage - Threshold":"5V","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"8-SON (3x3)","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.6000","priceTiers":[{"qty":1,"price":"$2.60000","currency":"USD"},{"qty":10,"price":"$2.33100","currency":"USD"},{"qty":25,"price":"$2.19960","currency":"USD"},{"qty":100,"price":"$1.87400","currency":"USD"},{"qty":250,"price":"$1.75960","currency":"USD"},{"qty":500,"price":"$1.53964","currency":"USD"},{"qty":1250,"price":"$1.27571","currency":"USD"},{"qty":2500,"price":"$1.24500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8b12e106fffde0cd8e50687639f4b04b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3851G50EDRBT/alternatives.json"},"ai":{"faq":[{"question":"Will TPS3851G50EDRBT drop into a board designed for TLV803EA29VDBZR?","answer":"Not without checking the pinout and threshold voltage.
