The push-pull output drives directly into a microcontroller reset pin without an external pull-up, and the 140ms minimum reset timeout gives the downstream logic time to stabilize after the last rail comes up. The three-channel monitoring in this footprint means a single IC replaces what would otherwise require three separate reset generators or a larger supervisor in a bigger package. ## Voltage thresholds and channel assignment The 3-channel count is the key spec: if your board has three distinct power domains that need sequencing or brownout detection, this part handles them in one SOT-23-8 footprint. The active-low reset output stays asserted until all three monitored voltages rise above their respective thresholds and the 140ms timeout expires. This glitch-free startup behavior prevents the processor from trying to execute code before the power supply is fully settled. Note that this part is listed as RoHS non-compliant. If your assembly requires RoHS exemption documentation or a lead-free alternative, confirm the compliance requirement before committing the BOM line.","metaTitle":"MAX6729KALTD3 Multi-Voltage Supervisor, SOT-23-8, 3 Channel","metaDescription":"MAX6729KALTD3 multi-voltage supervisor from Analog Devices, 3 monitored channels, active-low push-pull reset, 140ms timeout, SOT-23-8 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Type":"Multi-Voltage Supervisor","Reset":"Active Low","Output":"Push-Pull, Totem Pole","Package":"Bulk","Mounting Type":"Surface Mount","Reset Timeout":"140ms Minimum","Package / Case":"SOT-23-8","lifecycle_stage":"eol_hot","Voltage - Threshold":"3.075V, 4.625V, Adj","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"SOT-23-8","Number of Voltages Monitored":"3"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.74","stockQuantity":0,"priceTiers":[{"qty":110,"price":"$2.74000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a4d90b2ff3a6999812bd9ec183895b4c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What voltage thresholds does the MAX6729KALTD3 monitor?","answer":"It monitors three channels: two fixed thresholds at 3.075V and 4.625V, and one adjustable input that can be set with an external resistor divider."},{"question":"What is the reset output type and timeout?","answer":"The reset output is active-low, push-pull (totem pole), with a minimum reset timeout of 140ms."},{"question":"Is the MAX6729KALTD3 RoHS compliant?","answer":"No, this part is listed as RoHS non-compliant.
