The 100ms minimum reset timeout gives the power supplies time to ramp and the oscillator to stabilize before the processor starts executing code. This is longer than a simple power-on reset IC and suits systems with slow-starting regulators or large bulk capacitance on the output. The 8-SOIC package (3.90mm width) is a standard JEDEC footprint — the same land pattern used by countless other supervisors, op-amps, and interface ICs — so no board respin is needed if you swap from another 8-pin SOIC supervisor. Surface-mount assembly with the SOIC-8 body suits reflow soldering. The package is moisture-sensitive per J-STD-020; the floor life classification is not listed here, so standard MSL handling applies unless the reel label specifies otherwise.","metaTitle":"TI LMC6953CM/NOPB Multi-Voltage Supervisor, 3.3V/5V","metaDescription":"Texas Instruments LMC6953CM/NOPB multi-voltage supervisor monitors 3.3V and 5V rails with active-low open-drain reset. 100ms timeout, -40°C to 85°C, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Multi-Voltage Supervisor","Reset":"Active Low","Output":"Open Drain or Open Collector","Package":"Bulk","Mounting Type":"Surface Mount","Reset Timeout":"100ms Minimum","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Threshold":"3.3V, 5V","Operating Temperature":"-40°C ~ 85°C (TJ)","Supplier Device Package":"8-SOIC","Number of Voltages Monitored":"2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.28","stockQuantity":0,"priceTiers":[{"qty":132,"price":"$2.28000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/30ec8070ee30ead11721321966a579c4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reset output type and timeout?","answer":"The reset timeout is 100ms minimum, meaning the output stays low for at least 100ms after both monitored voltages rise above their thresholds."},{"question":"Does LMC6953CM/NOPB replace TL7702BID?","answer":"Not directly. The TL7702BID is a single-voltage supervisor with a 270ns propagation delay (not a fixed timeout) and supports both active-high and active-low reset outputs. The LMC6953CM/NOPB monitors two voltages (3.3V and 5V) with a 100ms timeout and only active-low reset.
