Key Features
- Adjustable push-button hold time (100 ms to 10 s) prevents accidental power-on or power-off events in consumer and industrial systems
- Interrupt output for menu-driven applications allows firmware to detect short button presses and trigger UI actions without dedicated microcontroller GPIO polling
- Wide 1.6 V to 26 V supply range in an ultra-compact 8-pin SOT-23 package supports battery-powered and wall-adapter systems with a single device
Applications
LTC2954CTS8-1#TRMPBF is ideal for portable consumer electronics, handheld industrial instruments, and medical devices that require reliable push-button power management with user-interface interrupt capability. Its adjustable hold-time prevents accidental shutdowns and enables long-press versus short-press differentiation for menu navigation. The wide supply voltage range and tiny SOT-23 footprint make it a drop-in solution for both single-cell Li-Ion at 3.7 V and multi-cell packs up to 26 V.

Frequently Asked Questions
What supply voltage range does LTC2954CTS8-1#TRMPBF support, and what hold-time range can be programmed?
LTC2954CTS8-1#TRMPBF operates from 1.6 V to 26 V and allows an adjustable push-button hold time from approximately 100 ms up to 10 s set by an external capacitor, enabling designers to distinguish accidental touches from intentional power events in handheld and portable systems.
How does the interrupt output on LTC2954CTS8-1#TRMPBF enable menu-driven user interfaces without additional logic?
The interrupt output pulses low on a short button press while the main power remains on, signaling the host microcontroller to advance a menu or wake from sleep without external debounce circuitry or FPGA logic, reducing the BOM by at least 2 passive components and simplifying firmware interrupt handling.
Which portable or industrial applications are best matched to LTC2954CTS8-1#TRMPBF?
Battery-operated instruments using single-cell Li-Ion at 3.7 V, multi-cell packs up to 26 V, and industrial handheld scanners benefit most from LTC2954CTS8-1#TRMPBF, as it handles power sequencing, glitch-free shutdown, and UI interaction in one 8-pin SOT-23 device operating across -40°C to 85°C without an external supervisor.
How does LTC2954CTS8-1#TRMPBF compare to discrete push-button circuits for power-on control?
A discrete implementation typically requires a P-channel MOSFET, a debounce RC network, and a latch circuit totaling 5 or more components, whereas LTC2954CTS8-1#TRMPBF integrates all functions in a single 8-pin SOT-23 package occupying under 10 mm² of PCB area, reducing assembly time and improving reliability in high-volume production.
