The open-drain output allows the reset signal to be wire-ORed with other reset sources, and the output is valid even when VDD is as low as 1.8V, which is useful for sequencing in multi-rail systems. ## Adjustable timeout — tuning out false resets The reset timeout is adjustable or selectable via an external capacitor on the CT pin, giving the designer control over the delay from supply recovery to reset release. A fixed-timeout reset IC would force a design compromise — too short a delay risks false resets during a slow ramp, too long delays system startup. The adjustable timeout on the TPS3808 series eliminates that trade-off without adding a separate timer IC. The threshold accuracy and reset timing are specified across this full range, which is critical for applications where a reset IC that drifts with temperature can cause intermittent system lockups. ## 6-WSON (2x2) — footprint and thermal reality The package is 6-WDFN exposed pad, 2x2 mm body. The 6-WDFN exposed pad package has a 2x2 mm body.","metaTitle":"TPS3808G33DRVR Simple Reset/Power-On Reset IC","metaDescription":"Texas Instruments TPS3808G33DRVR: Simple Reset/Power-On Reset, active-low open-drain output, 3.07V threshold, adjustable timeout, -40°C to 125°C, 6-WSON.","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":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"Adjustable/Selectable","Package / Case":"6-WDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3808","Voltage - Threshold":"3.07V","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"6-WSON (2x2)","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3f65002da94aeb5b2adfcd3958ef5148.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3808G33DRVR/alternatives.json"},"ai":{"faq":[{"question":"Is TPS3808G33DRVR compatible with 3.3V systems?","answer":"Yes.
