Programmable silicon oscillator in a TSOT-23-6 footprint
The LTC6992IS6-1#TRMPBF is part of Analog Devices' TimerBlox® family — a silicon oscillator that generates a programmable square-wave output from 3.81 Hz to 1 MHz without needing an external timing capacitor or crystal. It runs from a single 2.25 V to 5.5 V supply and draws 365 µA typical, making it well suited for battery-operated and space-constrained industrial controls, sensor timing, and power-converter clocking where a small footprint and low power matter more than sub-ppm accuracy.
Frequency range and what it means for the BOM
The 3.81 Hz to 1 MHz programmable range covers the vast majority of low- to mid-frequency timing needs — watchdog timebases, LED dimming PWM, DC-DC converter sync, and sensor sampling clocks. The lower bound down to 3.81 Hz lets you replace a discrete RC oscillator or a low-frequency crystal without adding a separate divider stage. At the top end, 1 MHz is enough for most switching regulators and simple logic clocks, but not for high-speed serial interfaces or processor core clocks.
Supply flexibility and current draw
The 2.25 V to 5.5 V supply range means this part runs off a single Li-ion cell (down to its near-empty voltage), a 3.3 V rail, or a 5 V logic rail without a separate regulator. Typical supply current of 365 µA is low enough to keep the oscillator running in always-on sensor nodes where every microamp counts, though it is not as aggressive as the sub-µA oscillators used in ultra-low-power sleep wakeups.
Package and mounting
Housed in a TSOT-23-6 (SOT-23-6 Thin) surface-mount package, which is a common footprint for small linear and timing ICs. The thin profile helps in tight enclosures.
