The open-drain topology allows the reset line to be shared with other supervisors or pulled up to a different logic voltage. ## Temperature range and threshold accuracy At 125°C junction, the threshold accuracy and output drive are still within the datasheet limits — a common derating concern for supervisors used near hot exhaust or turbocharger paths. The 3.3V threshold is the standard rail for automotive MCUs (e.g., TI TMS570, NXP S32K) and sensor supplies. The adjustable/selectable reset timeout lets the designer match the reset hold period to the power-up sequence of the downstream processor, avoiding premature release or brown-out chatter. ## Package and footprint for automotive PCB Supplied in an 8-VDFN exposed pad package, also designated 8-SON (3x3 mm). Mounting is surface-mount, compatible with standard reflow profiles. ROHS3 compliant. The base product number is TPS3852; the H33 suffix denotes the 3.3V threshold variant, and the QDRBRQ1 suffix encodes the 8-SON package and automotive qualification. The part can be scheduled into regular production without sourcing risk.","metaTitle":"TPS3852H33QDRBRQ1 – Texas Instruments Automotive Supervisor","metaDescription":"TPS3852H33QDRBRQ1 – Texas Instruments simple reset/power-on reset IC, automotive grade, AEC-Q100, 3.3V threshold, open-drain output, -40°C to 125°C, 8-SON","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","Grade":"Automotive","Reset":"Active Low","Output":"Open Drain or Open Collector","Series":"-","Package":"Tape & Reel (TR) Cut Tape (CT)","Mounting Type":"Surface Mount","Qualification":"AEC-Q100","Reset Timeout":"Adjustable/Selectable","Package / Case":"8-VDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3852","Voltage - Threshold":"3.3V","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"8-SON (3x3)","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3600","priceTiers":[{"qty":1,"price":"$2.36000","currency":"USD"},{"qty":10,"price":"$2.12000","currency":"USD"},{"qty":25,"price":"$2.00000","currency":"USD"},{"qty":100,"price":"$1.70380","currency":"USD"},{"qty":250,"price":"$1.59984","currency":"USD"},{"qty":500,"price":"$1.39986","currency":"USD"},{"qty":1000,"price":"$1.15988","currency":"USD"},{"qty":3000,"price":"$1.07989","currency":"USD"},{"qty":6000,"price":"$1.03990","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/32b2b84fd4a54f12da12dbdd82471663.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3852H33QDRBRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TPS3852H33QDRBRQ1 AEC-Q100 qualified and automotive grade?","answer":"Yes, the TPS3852H33QDRBRQ1 is AEC-Q100 qualified and listed with an Automotive grade.
