LTC6995MPS6-2#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6995MPS6-2#TRMPBF 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 internal master oscillator frequency is programmed via a single resistor, RSET, while an internal divider, NDIV, selectable from eight settings (1 to 2^21), determines the final output clock period. The device generates a 50% duty cycle square wave and includes a reset function to stop oscillation and clear dividers. This specific part number corresponds to the LTC6995-2 variant with active-low reset, housed in a 6-lead Plastic TSOT-23 package.

Programmable Timers And Oscillators Feature Summary

• Programmable period range from 1.024ms to 9.54 hours using one resistor and internal divider
• Active-low reset input (LTC6995-2) with selectable output polarity
• Low supply current ranging from 55µA to 80µA depending on configuration
• Operating temperature range of –55°C to 125°C

Programmable Timers And Oscillators Applications

• Power-On Reset Timers
• Watchdog Timers
• Long Time One Shot circuits
• Periodic Wake-Up Call generators
• Heartbeat Timers

Programmable Timers And Oscillators Procurement Notes

Verify the component against the official Analog Devices datasheet Rev. B specifications. Confirm the package type is 6-Lead Plastic TSOT-23 and the temperature grade is MP (-55°C to 125°C). Ensure the ordering suffix matches the tape and reel format required for production integration.

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 DIVCODE based on the desired NDIV and output polarity. Calculate RSET using the formula tOUT = (NDIV * RSET / 50kΩ) * 1.024ms. Ensure RSET tolerance is within 0.5% for optimal frequency accuracy.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6995 TimerBlox family of versatile silicon timing devices. The MPS6 suffix indicates the automotive-grade MP temperature range (-55°C to 125°C) and the S6 plastic TSOT-23 package. The -2 suffix designates the LTC6995-2 variant with active-low reset functionality, distinct from the -1 variant which uses active-high reset.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements include other variants within the LTC6995 family such as LTC6995IS6-2#TRMPBF or LTC6995HS6-2#TRMPBF, provided the operating temperature range requirements are met. Verify that the package dimensions and pinout remain compatible with the existing PCB layout.
