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, RSET, programs the LTC6995’s internal master oscillator frequency. The output clock period is determined by this master oscillator and an internal frequency divider, NDIV, 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
