The active-low open-drain output lets it pull the reset line low on fault and can be shared with other open-drain reset sources through a pull-up resistor. ## What the 10ms timeout buys the system The 10ms minimum reset timeout is the guaranteed low pulse width the part delivers when the monitored rail crosses the threshold. This gives downstream devices — an MCU, FPGA, or SoC — enough time to complete their internal reset sequence before the IC releases the rail. If the timeout were shorter than the processor's reset hold requirement, the system could start up in an undefined state. The 10ms floor covers most 8-bit and 32-bit microcontroller reset specifications. ## Package and temperature grade — board-fit and environment Housed in a SOT-23-5 (SC-74A) package, this is a five-pin surface-mount device that fits a standard 0.95 mm pitch footprint.","metaTitle":"TPS3838E18DBVRG4 Simple Reset/Power-On Reset IC","metaDescription":"Texas Instruments TPS3838E18DBVRG4 simple reset/power-on reset IC with active-low open-drain output.","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)","Mounting Type":"Surface Mount","Reset Timeout":"10ms Minimum","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Base Product Number":"TPS3838","Voltage - Threshold":"1.71V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/020841d6578f782f4748e70ad552a6db.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3838E18DBVRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between TPS3838E18DBVRG4 and TPS3838E18DBVT?","answer":"The difference is the packaging and reel format.
