LTC6993IDCB-2#TRPBF

Multivibrators Overview

The LTC6993IDCB-2#TRPBF is a monostable multivibrator from the TimerBlox family, housed in a 6-lead DFN package. It operates on a single supply voltage ranging from 2.25V to 5.5V with an operating temperature range of –40°C to 85°C. The device generates output pulses with widths programmable from 1µs to 33.6 seconds via a master oscillator and internal divider. It features rising-edge triggering with retrigger capability, allowing pulse extension by subsequent trigger signals.

Multivibrators Feature Summary

• Retriggerable monostable operation triggered by rising edges
• Programmable pulse width using external resistor and divider settings
• Configurable output polarity for positive or negative pulses
• Low power consumption suitable for battery-powered applications

Multivibrators Applications

• Watchdog timers
• Frequency discriminators
• Missing pulse detection
• Envelope detectors

Multivibrators Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the 'I' grade designation matches the required industrial temperature range of –40°C to 85°C for your application environment. Ensure compatibility with the 6-lead DFN footprint during PCB layout review.

Multivibrators Selection Notes

Select this variant specifically for its retriggerable functionality, which distinguishes it from non-retriggerable counterparts like the LTC6993-1. The IDCB package provides a compact surface-mount solution. Consider the DIV pin configuration requirements for setting the desired divider ratio and output polarity before finalizing the design.

Multivibrators Part Context

This component belongs to the Analog Devices TimerBlox family of silicon timing devices. It serves as a versatile one-shot pulse generator within the broader LTC6993 series, which includes variants with different trigger polarities and retrigger capabilities across various package options.

Multivibrators FAQ

How does the retrigger feature function?

The LTC6993-2 allows the output pulse to be extended indefinitely by additional rising-edge trigger signals occurring while the output is active.

What determines the output pulse polarity?

The polarity is determined by the DIVCODE value set via the DIV pin; a POL bit of 0 produces a positive pulse, while 1 produces a negative pulse.
