LTC6995CS6-2#TRPBF

Programmable Timers And Oscillators Overview

The LTC6995CS6-2#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) with eight settings from 1 to 221. A single resistor, RSET, programs the internal master oscillator frequency. The device 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
• Active-low reset input characteristic of the LTC6995-2 variant
• CMOS output driver capable of sourcing and sinking 20mA
• Low supply current consumption ranging from 55µA to 80µA depending on configuration

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 #TRPBF indicates tape and reel packaging when ordering. Confirm the -C grade corresponds to the 0°C to 70°C specified temperature range required for the application environment. Ensure the active-low reset logic of the -2 version aligns with system control signals.

Programmable Timers And Oscillators Selection Notes

Select the LTC6995-2 variant specifically for applications requiring an active-low reset signal. Use Table 1 in the datasheet to determine the correct resistor divider values for the DIV pin to set the desired NDIV and polarity. Calculate RSET based on the target frequency and selected divider ratio to ensure accuracy within ±1.5%.

Programmable Timers And Oscillators Part Context

This component belongs to the Analog Devices TimerBlox family of versatile silicon timing devices. The CS6 designation identifies the commercial temperature grade (-40°C to 85°C functional, 0°C to 70°C specified) housed in a 6-lead Plastic TSOT-23 package. The -2 suffix denotes the active-low reset functionality distinct from the -1 variant.

Programmable Timers And Oscillators Replacement Considerations

LTC6995IS6-2#TRPBF offers the same electrical functionality but with a wider specified operating temperature range of –40°C to 85°C compared to the commercial grade part.
