LTC6995HS6-2#WTRPBF

Programmable Timers And Oscillators Overview

The LTC6995HS6-2#WTRPBF 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 clock period is determined by an internal master oscillator and a programmable frequency divider (NDIV) with eight settings from 1 to 221. A single resistor, RSET, programs the internal master oscillator frequency. The device includes a reset function to stop the oscillator and clear dividers, with active-low reset logic specific to the -2 version. It operates on a single supply voltage ranging from 2.25V to 5.5V.

Programmable Timers And Oscillators Procurement Notes

Verify the automotive grade designation indicated by the #W suffix in the part number. Confirm the SOT-23 package type and tape and reel packaging format match the design requirements. Ensure the component meets the specified temperature range for the intended application environment.

Programmable Timers And Oscillators Selection Notes

Select the LTC6995-2 version when an active-low reset signal is required. Use Table 1 in the datasheet to determine the correct resistor values for the DIV pin to set the desired frequency divider and output polarity. Choose precision resistors for RSET to minimize frequency error, as accuracy depends heavily on resistor tolerance and temperature coefficient.

Programmable Timers And Oscillators Part Context

This component belongs to the Analog Devices TimerBlox family of versatile silicon timing devices. The HS6-2 designation indicates the H grade for extended temperature operation (-40°C to 125°C), the S6 package (TSOT-23), and the -2 variant with active-low reset functionality. The #W suffix denotes automotive qualification under AEC-Q100 standards.

Programmable Timers And Oscillators Replacement Considerations

LTC6995IS6-2#WTRPBF offers identical electrical characteristics but with an industrial temperature range (-40°C to 85°C) instead of the extended range.
