LTC6995IDCB-2#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6995IDCB-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 device operates on a single supply voltage between 2.25V and 5.5V with a typical supply current ranging from 55µA to 80µA depending on the clock period. It utilizes an internal master oscillator and a programmable frequency divider (NDIV) set via the DIV pin. The output is a 50% duty cycle square wave driven by a CMOS driver capable of sourcing or sinking 20mA. The component is housed in a 6-lead DFN package.

Programmable Timers And Oscillators Feature Summary

• Programmable period range from 1.024ms to 9.54 hours using a single RSET resistor and DIV pin configuration
• Active-low reset input characteristic of the LTC6995-2 version
• CMOS output driver with 20mA source/sink capability and selectable polarity
• Low power consumption with supply current as low as 55µA at 5.5V

Programmable Timers And Oscillators Applications

• Power-on reset timers
• Watchdog timers
• Long time one-shot circuits
• Periodic wake-up calls
• Heartbeat timers

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel mini packaging containing 500 units. Confirm the IDCB designation corresponds to the industrial temperature grade (-40°C to 85°C) and the DCB package type. Ensure the -2 suffix matches the requirement for an active-low reset input signal.

Programmable Timers And Oscillators Selection Notes

Select the LTC6995-2 variant when an active-low reset signal is required. Use Table 1 in the datasheet to determine the appropriate resistor values for the DIV pin to achieve the desired NDIV and output polarity. Calculate RSET based on the target output period and selected NDIV value to ensure frequency accuracy within specified limits.

Programmable Timers And Oscillators Part Context

This part belongs to the LTC6995 series of TimerBlox silicon oscillators. The IDCB suffix denotes the Industrial temperature range (-40°C to 85°C) and the 6-lead DFN package. The -2 suffix specifies the active-low reset logic, distinguishing it from the -1 version which uses active-high reset.

Programmable Timers And Oscillators Replacement Considerations

LTC6995IDCB-1#TRMPBF differs only in reset polarity (active-high vs active-low). LTC6995HDCB-2#TRMPBF offers an extended high-temperature range (-40°C to 125°C). Verify electrical compatibility and thermal requirements before substitution.
