The LTC6993 is part of the TimerBlox family of versatile silicon timing 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. tOUT=NDIV RSET50k 1 s, NDIV = 1, 8, 64,..,221 The output pulse is initiated by a transition on the trigger input (TRIG).
2 Each part can be configured to generate posi-tive or negative output pulses. The LTC6993 is available in four versions to provide different trigger signal polarity and retrigger POLARITYRETRIGGERLTC6993-1 Rising-EdgeNoLTC6993-2 Rising-EdgeYesLTC6993-3 Falling-EdgeNoLTC6993-4 Falling-EdgeYesThe LTC6993 also offers the ability to dynamically adjust the width of the output pulse via a separate control easy configuration of the LTC6993, download the TimerBlox Designer tool at DetectorapplicaTions nPulse Width Range: 1 s to Seconds nConfigured with 1 to 3 Resistors nPulse Width Max Error: n< for Pulse Width > 512 s n< for Pulse Width of 8 s to 512 s n< for Pulse Width of 1 s to 8 s nFour LTC6993 Options Available.
