The reset timeout is adjustable via an external capacitor, giving the designer control over power-up and brown-out recovery timing without changing the supervisor part number. ## Automotive-grade monitoring for under-hood environments This part is qualified to AEC-Q100, making it suitable for automotive applications including engine control units, transmission controllers, and body electronics. The 10-VSON (3x3) package with exposed pad helps conduct heat to the PCB ground plane. ## Open-drain output for system reset consolidation The open-drain output allows multiple reset supervisors to share a common pull-up resistor, enabling a wired-OR configuration for system-level reset consolidation. This is useful when several voltage rails must be monitored and any one fault should trigger a global reset. The output is active-low, matching the reset polarity of most MCUs, DSPs, and FPGAs.","metaTitle":"TI TPS3850H50QDRCRQ1 Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3850H50QDRCRQ1: automotive AEC-Q100 simple reset IC, 5V threshold, active-low open-drain output, adjustable timeout, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"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":"Automotive, AEC-Q100","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":"5V","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"10-VSON (3x3)","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2735","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6375c28393fffa2100da42d2bb5990ce.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3850H50QDRCRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TPS3850H50QDRCRQ1 AEC-Q100 qualified?","answer":"Yes, the TPS3850H50QDRCRQ1 is part of the Automotive, AEC-Q100 series, making it qualified for automotive applications."},{"question":"What is the reset timeout of TPS3850H50QDRCRQ1?","answer":"The reset timeout is adjustable/selectable via an external capacitor, allowing the designer to set the delay between the supply crossing the threshold and the reset output de-asserting."},{"question":"Can TPS3850H50QDRCRQ1 be used with an open-drain output?","answer":"Yes, the output is specified as Open Drain or Open Collector, active-low.
