It asserts a reset signal on power-up, power-down, and brown-out conditions, preventing code corruption or logic glitches in the processor. The open-drain output with active-low polarity lets it interface directly with the reset input of most MCUs, DSPs, or FPGAs, and the SC-70-3 package keeps the footprint small enough for space-constrained designs like sensor nodes or portable instruments. ## 1.665V threshold — matching the rail The 1.665V threshold is set for monitoring low-voltage core supplies, common in 1.8V nominal rails where the supervisor must trip before the processor's minimum operating voltage. If your BOM has a 1.8V LDO feeding a Cortex-M core, this part catches the brown-out before the MCU starts executing garbage. The threshold is fixed internally — no resistor divider to trim, which saves two passives and one potential failure point. ## 140ms reset timeout — why it matters The minimum 140ms reset timeout gives the main supply and oscillator time to fully settle before the processor starts fetching code. In designs with a slow-start LDO or a ceramic-cap regulator that takes tens of milliseconds to reach regulation, that 140ms window avoids a reset-release race that can cause first-instruction corruption. For a battery-powered device waking from deep sleep, the timeout also ensures the processor doesn't attempt to run before the supply has finished ramping. ## Temperature range and deployment Rated for -40°C to 85°C ambient, this part fits indoor industrial equipment, outdoor telecom enclosures, and factory-floor controllers that see seasonal temperature swings. It is not specified for automotive under-hood or downhole environments — those would need a wider-temperature or AEC-Q100 qualified supervisor. The SC-70-3 package is small enough for a sensor module or a compact PLC I/O card. ## Active lifecycle, no LTB risk The MAX6834IXRD3+T carries an Active product status and is ROHS3 compliant. For a BOM freeze, this part is safe to specify into new production runs without worrying about a mid-lifecycle swap.","metaTitle":"MAX6834IXRD3+T Simple Reset/Power-On Reset SC-70-3","metaDescription":"MAX6834IXRD3+T from Analog Devices is a simple reset/power-on reset IC with active-low open-drain output, 1.665V threshold, 140ms min timeout, SC-70-3 package","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Open Drain or Open Collector","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"140ms Minimum","Package / Case":"SC-70, SOT-323","lifecycle_stage":"eol_hot","Voltage - Threshold":"1.665V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"SC-70-3","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.81","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.81000","currency":"USD"},{"qty":10,"price":"$2.52800","currency":"USD"},{"qty":25,"price":"$2.38480","currency":"USD"},{"qty":100,"price":"$2.03200","currency":"USD"},{"qty":250,"price":"$1.90800","currency":"USD"},{"qty":500,"price":"$1.66950","currency":"USD"},{"qty":1000,"price":"$1.38330","currency":"USD"},{"qty":2500,"price":"$1.35000","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/max6832-max6840.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MAX6834IXRD3+T active low or active high reset?","answer":"The reset output is active low.
