Product Overview

The LTC6991CS6#TRMPBF is a resettable low Frequency Oscillator with a programmable period range of 1.024ms to 9.54 hours (29.1µHz to 977Hz), specifically intended for long duration timing events. The LTC6991 is part of the TimerBlox® family of versatile silicon timing devices. A single resistor, RSET programs the LTC6991's internal master oscillator frequency. The output clock period is determined by this master oscillator and an internal frequency divider, NDIV, programmable to eight settings from 1 to 2²¹. The active/inactive voltage levels depend on the POL bit setting. When first powered up, the output is held low. If the polarity is set for non-inversion (POL = 0) and the output is enabled (RST = 0) at the end of the start-up time, OUT will begin oscillating. The output latch reset function provided by the RST pin allows the LTC6991 to enable a larger system at regular intervals.
