That window gives the downstream microcontroller or FPGA time to complete a clean shutdown or to stabilise its own power-on sequence before the reset de-asserts. In a battery-backup context, the timeout also masks the switch-over transient when the backup source engages. No AEC-Q automotive qualification is listed, so it is not specified for under-hood or chassis-domain applications.","metaTitle":"TPS3620-50DGKR Battery Backup Circuit, Active Low Reset","metaDescription":"Texas Instruments TPS3620-50DGKR Battery Backup Circuit with active low push-pull reset, 4.55V threshold, 60ms min reset timeout.","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":"4.55V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"8-VSSOP","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5690","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ae93676fcfae3cff35626cc09a4a46ae.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3620-50DGKR/alternatives.json"},"ai":{"faq":[{"question":"Does TPS3620-50DGKR have an active low reset?","answer":"Yes. The reset output is active low and uses a push-pull (totem pole) topology, so it does not require an external pull-up resistor. It drives the reset pin of the downstream device directly."},{"question":"What is the reset timeout for TPS3620-50DGKR?","answer":"The reset timeout is a minimum of 60 ms.
