LTC6995HS6-1#WTRMPBF

Programmable Timers And Oscillators Overview

The LTC6995HS6-1#WTRMPBF is a silicon oscillator from the TimerBlox family, designed for long-duration timing events. It features a programmable period range of 1.024ms to 9.54 hours (29.1µHz to 977Hz). The output frequency is set by a single resistor on the SET pin and an internal divider controlled by the DIV pin voltage. Key electrical parameters include a supply voltage range of 2.25V to 5.5V, supply current between 55µA and 80µA depending on configuration, and a maximum frequency accuracy of ±1.5%. The device operates within a temperature range of –40°C to 125°C and is housed in a 6-lead TSOT-23 package.

Programmable Timers And Oscillators Procurement Notes

Verify that the #W suffix indicates automotive grade qualification. Confirm the HS6 designation corresponds to the high-temperature industrial range (-40°C to 125°C) and the S6 package type. Ensure the -1 suffix matches the required active-high reset logic polarity for the specific circuit design.

Programmable Timers And Oscillators Selection Notes

Select this part when a wide timing range up to several hours is required without external crystals. Use the LTC6995-1 variant if an active-high reset signal is needed. Choose the HS6 package version for applications requiring operation up to 125°C. Calculate RSET based on the desired period and selected NDIV value to optimize current consumption.

Programmable Timers And Oscillators Part Context

This component belongs to the Analog Devices TimerBlox family of versatile silicon timing devices. It serves as a low-frequency oscillator alternative to discrete RC circuits or crystal oscillators where extreme precision is not critical but long timing intervals are necessary. The HS6-1#WTRMPBF is the tape and reel version of the automotive-grade, high-temperature industrial variant.
