The LTC6992IS6-4#TRMPBF is a programmable silicon oscillator from the TimerBlox® family, covering 3.81 Hz to 1 MHz with a single external resistor setting the frequency. It operates from 2.25 V to 5.5 V and draws 365 µA typical supply current — low enough for battery-powered instrumentation and portable equipment. The TSOT-23-6 package fits tight PCB layouts where a crystal or MEMS oscillator would consume more board area. The -4 suffix indicates the output polarity and duty-cycle configuration variant within the LTC6992 family.
The 3.81 Hz to 1 MHz programmable range covers low-frequency watchdog timers, PWM generation, and clock synthesis up to the low-MHz region. The 365 µA supply current at no load is the quiescent floor — actual system power depends on the output load capacitance and frequency, but this part avoids the higher current draw of a crystal oscillator plus buffer. Supply voltage tolerance from 2.25 V to 5.5 V means the same BOM line can serve both 3.3 V and 5 V rails without a separate regulator. The TSOT-23-6 footprint is a standard SOT-23-6 variant — confirm the land pattern matches the thin-body package (1.1 mm max height) for pick-and-place clearance.
Active lifecycle and compliance status
It is ROHS3 compliant, meeting current EU restriction requirements for lead and other substances. The part is supplied in Tape & Reel (TR) and Cut Tape (CT) options for both volume and prototyping quantities. Analog Devices is the sole manufacturer; no direct second-source exists for this exact order code.
Package and mounting considerations
The TSOT-23-6 package (SOT-23-6 Thin) is a surface-mount footprint with 0.95 mm pitch. The thin profile suits height-constrained enclosures. No exposed thermal pad — thermal management is through the PCB copper and the package body. Standard reflow profiles for SOT-23-6 apply; no special moisture sensitivity level is listed, but standard MSL 1 handling is typical for this package family.
