TimerBlox: Long Timer, Low

Frequency Oscillator

FEATURES

DESCRIPTION

The LTC^®6995 is a silicon oscillator with a programmable

periodrangeof1.024msto9.54hours(29.1µHzto977Hz),

specifically intended for long duration timing events. The

LTC6995 is part of the TimerBlox^®family of versatile

silicon timing devices.

Period Range: 1ms to 9.5 Hours

Timing Reset by Power-On or Reset Input

Configured with 1 to 3 Resistors

AEC-Q100 Qualified for Automotive Applications

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.

APPLICATIONS

Power-On Reset Timer

Long Time One Shot

“Heartbeat” Timers

Watchdog Timers

Periodic “Wake-Up” Call

High Vibration, High Acceleration Environments

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.
