LTC6995MPS6-2#TRPBF

Programmable Timers And Oscillators Overview

The LTC6995MPS6-2#TRPBF 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, which offers eight settings from 1 to 2^21. Frequency is programmed via a single resistor, RSET, connected between the SET and GND pins. The device includes a reset function to stop oscillation and clear dividers, with active-low reset polarity specific to the -2 version. It operates on a single supply voltage ranging from 2.25V to 5.5V.

Programmable Timers And Oscillators Feature Summary

• Programmable period range from 1.024ms to 9.54 hours using a single external resistor

• Heartbeat timers

Programmable Timers And Oscillators Procurement Notes

Verify the component is the Automotive grade MPS6 variant with –55°C to 125°C operating temperature. Confirm the suffix #TRPBF indicates Tape and Reel packaging. Ensure the -2 designation matches the required active-low reset logic. Check for AEC-Q100 qualification status if automotive reliability reports are required for the specific manufacturing lot.

Programmable Timers And Oscillators Selection Notes

Select the LTC6995-2 version when an active-low reset signal is required. Choose the MPS6 package variant for applications requiring operation in extreme temperatures from –55°C to 125°C. Use Table 1 in the datasheet to determine the correct resistor values for the DIV pin to set the desired NDIV and output polarity. Calculate RSET based on the target period and selected NDIV to ensure frequency accuracy within ±1.5% maximum error.

Programmable Timers And Oscillators Part Context

This part belongs to the Analog Devices TimerBlox family of versatile silicon timing devices. The MPS6 suffix identifies the specific temperature grade and TSOT-23 package configuration. The -2 suffix distinguishes it from the -1 version by defining the reset input polarity as active low rather than active high. Both versions share identical oscillator performance and programming interfaces.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements must match the -2 reset polarity and MPS6 temperature/package specifications. Other TimerBlox parts like the LTC6990 or LTC6992 offer different frequency ranges or functionalities such as VCO operation but do not provide the same long-period timer capabilities without additional circuitry.
