Open-drain allows multiple reset sources to share a common pull-up and a wired-OR connection to the processor's reset pin. The reset timeout is adjustable/selectable via an external capacitor on the CT pin — the designer sets the pulse width to match the downstream device's reset hold-time requirement. This is a flexible alternative to fixed-timeout supervisors, though it adds one external component. Housed in a SOT-23-6 package, this is a compact footprint suited for space-constrained boards. Note that it is not listed as AEC-Q100 qualified — verify with the datasheet if you need automotive-grade screening.","metaTitle":"TPS3808G18DBVRG4 Simple Reset IC, 1.67V Threshold, SOT-23-6","metaDescription":"Texas Instruments TPS3808G18DBVRG4 simple reset/power-on reset IC, active-low open-drain output, 1.67V threshold, adjustable timeout, SOT-23-6.","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 Low","Output":"Open Drain or Open Collector","Series":"-","Package":"Tape & Reel (TR)","Mounting Type":"Surface Mount","Reset Timeout":"Adjustable/Selectable","Package / Case":"SOT-23-6","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"TPS3808","Voltage - Threshold":"1.67V","Operating Temperature":"-40°C ~ 125°C (TJ)","Supplier Device Package":"SOT-23-6","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3f65002da94aeb5b2adfcd3958ef5148.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3808G18DBVRG4/alternatives.json"},"ai":{"faq":[{"question":"Is TPS3808G18DBVRG4 obsolete?","answer":"Yes, the TPS3808G18DBVRG4 is listed as Obsolete.
