DESCRIPTION
TimerBlox: Monostable
Pulse Generator (One Shot)
The LTC6993 is a monostable multivibrator (also known
as a “one-shot” pulse generator) with a programmable
pulse width of 1s to 33.6 seconds. The LTC6993 is part
oftheTimerBloxfamilyofversatilesilicontimingdevices.
A single resistor, RSET, programs an internal master os-
cillator frequency, setting the LTC6993’s time base. The
output pulse width is determined by this master oscillator
and an internal clock divider, NDIV, programmable to eight
settings from 1 to 221.

1s, NDIV = 1, 8, 64,...,221
The output pulse is initiated by a transition on the trigger
input(TRIG).Eachpartcanbeconfiguredtogenerateposi-
tive or negative output pulses. The LTC6993 is available
in four versions to provide different trigger signal polarity
and retrigger capability.

The LTC6993 also offers the ability to dynamically adjust
the width of the output pulse via a separate control voltage.
