LTC6993 - TimerBlox: Monostable Pulse Generator (One Shot)

The LTC®6993 is a monostable multivibrator (also known as 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.

A single resistor, RSET, programs an internal master oscillator 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.
