TimerBlox: Monostable

Pulse Generator (One Shot)

FEATURES

DESCRIPTION

TheLTC^®6993isamonostablemultivibrator(alsoknownas

a “one-shot” pulse generator) with a programmable pulse

width of 1µs to 33.6 seconds. The LTC6993 is part of the

TimerBlox™ family of versatile silicon timing devices.

Pulse Width Range: 1µs to 33.6 Seconds

Configured with 1 to 3 Resistors

Pulse Width Max Error:

– <2.3% for Pulse Width > 512µs

– <3.4% for Pulse Width of 8µs to 512µs

– <4.9% for Pulse Width of 1µs to 8µs

Four LTC6993 Options Available:

A single resistor, R , programs an internal master os-

SET

cillator frequency, setting the LTC6993’s time base. The

output pulse width is determined by this master oscillator

– Rising-Edge or Falling-Edge Trigger

– Retriggerable or Non-Retriggerable

and an internal clock divider, N , programmable to eight

DIV

settings from 1 to 2 .

Configurable for Positive or Negative Output Pulse

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.
