Housed in a 5-pin SOT-23-5 (SC-74A) package, the footprint is a standard 0.95 mm pitch with a 2.9 mm × 1.6 mm body — a direct fit for space-constrained automotive PCBs where a supervisor must sit close to the processor supply pin.","metaTitle":"TPS3837K33QDBVRQ1 Simple Reset IC, 2.93V Threshold, AEC-Q100","metaDescription":"Texas Instruments TPS3837K33QDBVRQ1 automotive-grade simple reset/power-on reset IC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Type":"Simple Reset/Power-On Reset","Reset":"Active High","Output":"Push-Pull, Totem Pole","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"10ms Minimum","Package / Case":"SC-74A, SOT-753","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"TPS3837","Voltage - Threshold":"2.93V","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/68d1b04baa1f77f05c58f33d1d1c1cf9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3837K33QDBVRQ1/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for TPS3837K33QDBVRQ1?","answer":"No official replacement is listed.
