The LTC6995 is a silicon oscillator with a programmable period range of 1.024ms to 9.54 hours (29.1μHz to 977Hz), specifically intended for long duration timing events. The LTC6995 is part of the TimerBlox^® family of versatile silicon timing devices.

A single resistor, R_SET, programs the LTC6995’s internal master oscillator frequency. The output clock period is determined by this master oscillator and an internal frequency divider, N_DIV, programmable to eight settings from 1 to 2²¹.

When oscillating, the LTC6995 generates a 50% duty cycle square wave output. A reset function is provided to stop the master oscillator and clear internal dividers. Removing reset initiates a full output clock cycle which is useful for programmable power-on reset and watchdog timer applications.

The LTC6995 has two versions of reset functionality. The reset input is active high for the LTC6995-1 and active low for the LTC6995-2. The polarity of the output when reset is selectable for both versions.

Applications

Power-On Reset Timer
Long Time One Shot
“Heartbeat” Timers
Watchdog Timers
Periodic “Wake-Up” Call
High Vibration, High Acceleration Environments
