The LTC6993IS6-1#PBF is a Monostable Pulse Generator (one shot) 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. A trigger signal on the TRIG input will force the output to the active (unstable) state for a programmable duration. This type of circuit is commonly referred to as a one-shot pulse generator. The simplest and most accurate method to program the LTC6993 is to use a single resistor, RSET, between the SET and GND pins. The control voltage can be generated by a DAC (digital-to-analogue converter), resulting in a digitally-controlled pulse width.
