LTC6995IDCB-1

Programmable Timers And Oscillators Overview

The LTC6995IDCB-1 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 (RSET) and an internal divider (NDIV) selectable via the DIV pin. Key electrical parameters include a supply voltage range of 2.25V to 5.5V, supply current between 55µA and 135µA depending on configuration, and maximum frequency accuracy of ±1.5%. The device operates within a temperature range of –40°C to 85°C and 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
• Internal frequency divider with eight settings (NDIV = 1 to 221) selected via DIV pin voltage
• Active-high reset input (LTC6995-1 variant) with selectable output polarity
• CMOS output driver capable of sourcing/sinking 20mA

Programmable Timers And Oscillators Applications

• Power-on reset timers
• Watchdog timers
• Long time one-shot circuits
• Periodic wake-up call generators
• Heartbeat timers for high vibration environments

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix #PBF or #TRMPBF against the required packaging format, as the base model number does not specify tape-and-reel versus tube quantities. Confirm the 'I' grade designation matches the required –40°C to 85°C operating temperature range for the target application environment.

Programmable Timers And Oscillators Selection Notes

Select the LTC6995IDCB-1 when an active-high reset signal is required; the LTC6995-2 variant uses an active-low reset. Ensure the DIV pin voltage divider network provides a ratio accurate to ±1.5% to guarantee correct NDIV selection. Use precision resistors for RSET to maintain the specified frequency accuracy over temperature.

Programmable Timers And Oscillators Part Context

This component belongs to the Analog Devices TimerBlox family of versatile silicon timing devices. The IDCB-1 designation specifically indicates the industrial temperature grade (-40°C to 85°C), the DCB plastic DFN package (2mm x 3mm), and the -1 variant with active-high reset functionality.
