That footprint is small enough to tuck next to the processor without consuming board real estate. ## Reset timeout — not specified in this listing The evidence does not list a reset timeout period for this order code. If the design requires a guaranteed minimum reset pulse width, the datasheet should be consulted for the specific timeout value of the TPS389033 variant.","metaTitle":"TPS389033GQDSERQ1 Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS389033GQDSERQ1 automotive simple reset IC, 3.3V threshold, active-low open-drain output, -40°C to 125°C, 6-WSON package.","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":"Bulk","Mounting Type":"Surface Mount","Reset Timeout":"-","Package / Case":"6-WFDFN","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS389033","Voltage - Threshold":"3.3V","Operating Temperature":"-40°C ~ 125°C (TJ)","Supplier Device Package":"6-WSON (1.5x1.5)","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e88caecb1ed0e0865cfa2cf4fbee4f99.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS389033GQDSERQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TPS389033GQDSERQ1 automotive qualified?","answer":"Yes, it is part of the Automotive, AEC-Q100 series, meaning it has been qualified for automotive-grade reliability and temperature requirements."},{"question":"Does TPS389033GQDSERQ1 have a reset timeout?","answer":"The evidence for this specific order code does not list a reset timeout value.
