APPLICATIONS INFORMATION
LTC6991 as “Wake-Up Timer”
The output latch reset function provided by the RST pin
allows the LTC6991 to enable a larger system at regular
intervals. The on-time can be controlled by the system.
This allows the system to shut itself down immediately
after performing its tasks, reducing power consumption.
Figure 12 shows an example using “black boxes” for a
switching regulator and the system being duty-cycled.
In some cases, an RC filter may be necessary at the RST

input to filter start-up glitches from the system as it is
powered on.
If the LTC6991 is enabling a switching regulator that can
operate on supplies greater than 5.5V, it will be necessary
to limit the supply voltage provided to the LTC6991. If
the LTC6991 output is not heavily loaded, and if a large
RSET resistor is used, the supply current will not be much
larger than 100μA, so a simple regulator circuit can be
constructed using a Zener diode.
