Nine selectable threshold combinations cover common voltage pairs without external resistor dividers. The open-drain output stays low for a minimum of 140 ms after both rails recover, giving the downstream MCU or FPGA time to stabilize its internal regulators and clock before release. That minimum timeout is the number to design around for your system's power-on reset hold time. Industrial temperature range (-40°C to 85°C) covers factory automation, telecom infrastructure, and outdoor base station equipment. ## Package and layout considerations Housed in an 8-lead DFN with exposed pad (3 mm × 2 mm body), the LTC2905IDDB#TRMPBF requires a thermal via pattern under the pad for proper soldering and heat transfer. The exposed pad is typically tied to ground on the PCB. Surface-mount assembly is standard, but the small pitch means solder paste stencil aperture should match the datasheet land pattern recommendation to avoid bridging. ## Lifecycle and sourcing No end-of-life notice or last-time-buy window has been announced. For current BOMs, the LTC2905IDDB#TRMPBF can be specified into new designs without near-term LTB risk.","metaTitle":"LTC2905IDDB#TRMPBF Multi-Voltage Supervisor, 140ms Reset","metaDescription":"LTC2905IDDB#TRMPBF multi-voltage supervisor from ADI, monitors 2 channels with 9 selectable thresholds, active-low open-drain output, 140ms min reset timeout","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Type":"Multi-Voltage Supervisor","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":"8-WFDFN Exposed Pad","lifecycle_stage":"eol_hot","Voltage - Threshold":"9 Selectable Threshold Combinations","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-DFN (3x2)","Number of Voltages Monitored":"2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.98","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.98000","currency":"USD"},{"qty":10,"price":"$4.47100","currency":"USD"},{"qty":25,"price":"$4.22680","currency":"USD"},{"qty":100,"price":"$3.66330","currency":"USD"},{"qty":250,"price":"$3.47540","currency":"USD"},{"qty":500,"price":"$3.11848","currency":"USD"},{"qty":1000,"price":"$2.63004","currency":"USD"},{"qty":2500,"price":"$2.49854","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/29045fd.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the pin-compatible alternatives to LTC2905IDDB#TRMPBF?","answer":"The ADM6305D3ARJZ1-RL7 from Analog Devices is a functional peer with the same active-low open-drain output and 140 ms minimum reset timeout, but it operates over a -40°C to 125°C range and comes in an SOT-23 package rather than DFN.
