It asserts an active-low reset output (push-pull, totem pole) when the monitored voltage drops below threshold, and holds reset for a minimum of 60ms after the supply returns. ## Threshold and Reset Timing The 4.55V threshold is a precision trip point for a nominal 5V supply — it triggers before the rail drops to an unreliable level for logic or memory, giving the backup battery time to take over. The 60ms minimum reset timeout ensures the micro or memory has fully settled before release, preventing brownout glitches on power-up. With an active-low, push-pull output, the reset signal drives directly into the enable or reset pin of an MCU, FPGA, or RTC without needing an external pull-up resistor. The push-pull stage sinks and sources current cleanly, which simplifies the BOM on the supervisor interface. The small footprint leaves board space for the backup battery and its charging circuit.","metaTitle":"Texas Instruments TPS3617-50DGKG4 Battery Backup Circuit","metaDescription":"Battery Backup Circuit supervisor with active-low reset, push-pull output, 4.55V threshold. 8-VSSOP package, -40°C to 85°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":"Battery Backup Circuit","Reset":"Active Low","Output":"Push-Pull, Totem Pole","Series":"-","Package":"Tube","Mounting Type":"Surface Mount","Reset Timeout":"60ms Minimum","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Base Product Number":"TPS3617","Voltage - Threshold":"4.55V","Operating Temperature":"-40°C~85°C(TJ)","Supplier Device Package":"8-VSSOP","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b94f173724737950b63ddf5a42a7cec9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3617-50DGKG4/alternatives.json"},"ai":{"faq":[{"question":"Does the TPS3617-50DGKG4 have an active low reset output?","answer":"Yes, the reset output is active-low and push-pull (totem pole), meaning it drives low when the monitored voltage drops below the 4.55V threshold.
