The 8-DFN (3x2 mm) package with exposed pad is small enough for handheld or space-constrained PCBs, but the pad needs a thermal via pattern to the ground plane for heat sinking. ## Pinout and integration note The 8-DFN pinout is standard for the LTC2954 family: the push-button input, the enable output (pulls high to start the system), the kill input for a forced shutdown, and the supply/ground pins. The exposed pad is tied to ground internally — make sure the PCB footprint includes a thermal via array under the pad to keep the junction temperature within limits when the part is switching a capacitive load on the enable line.","metaTitle":"LTC2954IDDB-2#TRMPBF Push Button On/Off Controller","metaDescription":"LTC2954IDDB-2#TRMPBF push button on/off controller from Analog Devices. 6 µA supply, 2.7V to 26.4V range, -40°C to 85°C, 8-DFN package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"Push Button, On/Off Controller","Mounting Type":"Surface Mount","Package / Case":"8-WFDFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Supply":"6 µA","Voltage - Supply":"2.7V ~ 26.4V","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"8-DFN (3x2)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.18","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.18000","currency":"USD"},{"qty":10,"price":"$5.58100","currency":"USD"},{"qty":25,"price":"$5.32120","currency":"USD"},{"qty":100,"price":"$4.62030","currency":"USD"},{"qty":250,"price":"$4.41268","currency":"USD"},{"qty":500,"price":"$4.02334","currency":"USD"},{"qty":1000,"price":"$3.50420","currency":"USD"},{"qty":2500,"price":"$3.37441","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/2954fb.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How does LTC2954IDDB-2 compare to LTC2954-1?","answer":"The LTC2954IDDB-2 and LTC2954IDDB-1 share the same package, supply range, and temperature grade. The difference is in the turn-off timing: the -2 variant provides a programmable power-down interrupt window before shutting off, while the -1 turns off immediately on button release.
