LTC6993HDCB-3#TRMPBF

Multivibrators Overview

The LTC6993HDCB-3#TRMPBF is a monostable multivibrator from the TimerBlox family, packaged in a 6-lead DFN. It generates output pulses with widths ranging from 1µs to 33.6 seconds. The pulse width is programmed using a single resistor (RSET) and an internal divider setting (NDIV). This specific variant features falling-edge trigger sensitivity and non-retriggerable operation. It operates on a single supply voltage between 2.25V and 5.5V.

Multivibrators Feature Summary

• Configurable for falling-edge triggering with non-retriggerable functionality
• Programmable pulse width via external resistor and internal clock divider
• Capable of generating positive or negative output pulses through polarity control
• Fast recovery time allows rapid readiness for subsequent trigger events

Multivibrators Applications

• Watchdog timer circuits
• Frequency discriminators
• Missing pulse detection systems
• Envelope detectors
• High vibration or acceleration environments

Multivibrators Procurement Notes

Verify the component matches the exact suffix #TRMPBF for tape and reel mini packaging. Confirm the temperature grade 'H' corresponds to the required -40°C to 125°C operating range. Ensure the DFN package dimensions align with the PCB footprint specifications. Check for automotive qualification requirements if applicable, as standard versions differ from W-suffix parts.

Multivibrators Selection Notes

Select this part when falling-edge trigger activation is required without retriggering capabilities. The H-grade version is necessary for industrial applications requiring operation up to 125°C. Verify that the desired pulse width range fits within the 1µs to 33.6 seconds limit defined by the RSET and NDIV settings. Consider the low profile DFN package for space-constrained designs.

Multivibrators Part Context

This device belongs to the Analog Devices TimerBlox family of silicon timing devices. It serves as a versatile one-shot pulse generator. The HDCB-3 designation indicates the high-temperature grade, DFN package, and specific trigger/polarity configuration within the broader LTC6993 series.

Multivibrators Replacement Considerations

LTC6993IDCB-3#TRMPBF offers identical electrical characteristics but is rated for commercial temperatures (-40°C to 85°C). LTC6993CDCB-3#TRMPBF is suitable for industrial applications limited to 0°C to 70°C. Substituting these requires verifying that the ambient temperature conditions do not exceed their respective maximum ratings.
