The reset output is active-low and push-pull, meaning it can sink or source current directly to the MCU reset pin without an external pull-up resistor. ## 60ms reset timeout — why it matters for boot reliability A timeout shorter than the supply ramp time risks brown-out on every power cycle; 60ms is a common sweet spot for MCU-based designs with ceramic bypass caps and moderate load capacitance. The part monitors a single voltage rail, so it is a good fit for single-supply MCUs or as the primary supervisor in a multi-rail system where the other rails are sequenced from the main supply. The 8-VSSOP package (3.00 mm width) is a small footprint that reflows well and is inspectable under a microscope — the 0.65 mm pitch is hand-solderable with a fine tip if needed. Surface-mount in an 8-TSSOP or 8-MSOP footprint — the 8-VSSOP supplier device package is the same mechanical outline. The exposed pad is not present on this package, so rework is straightforward: hot air at 290°C for 20 seconds lifts the part cleanly without cooking adjacent components.","metaTitle":"TPS3620-33DGKR Battery Backup Circuit, 2.93V Threshold","metaDescription":"Texas Instruments TPS3620-33DGKR battery backup supervisor IC. 2.93V threshold, active-low push-pull reset, 60ms timeout, 8-VSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Type":"Battery Backup Circuit","Reset":"Active Low","Output":"Push-Pull, Totem Pole","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"60ms Minimum","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3620","Voltage - Threshold":"2.93V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"8-VSSOP","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.9400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ae93676fcfae3cff35626cc09a4a46ae.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3620-33DGKR/alternatives.json"},"ai":{"faq":[{"question":"Does TPS3620-33DGKR have a push-pull output and active-low reset?","answer":"Yes.
