LTC6993MPS6-2#TRMPBF

Multivibrators Overview

The LTC6993MPS6-2#TRMPBF is a monostable multivibrator from the TimerBlox family, housed in a 6-lead Plastic TSOT-23 package. It operates on a single supply voltage ranging from 2.25V to 5.5V with an operating temperature range of –55°C to 125°C. The device features a programmable pulse width from 1µs to 33.6 seconds, determined by a master oscillator and an internal clock divider (NDIV) selectable from 1 to 221. It utilizes a rising-edge trigger input and supports retriggering functionality.

Multivibrators Feature Summary

• Retriggerable monostable operation triggered by rising-edge signals
• Programmable output pulse width via external resistor and internal 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 circuits
• Envelope detectors
• Timing elements in high vibration environments

Multivibrators Procurement Notes

Verify the specific suffix MPS6-2 corresponds to the MP grade (-55°C to 125°C) and retriggerable rising-edge configuration. Confirm the #TRMPBF indicates Tape and Reel Mini packaging. Check for automotive qualification requirements if applicable, as standard MP parts differ from W-tracked automotive versions.

Multivibrators Selection Notes

Select this variant when extended industrial temperature ranges below -40°C are required alongside retriggerable rising-edge triggering. Ensure the application benefits from the low profile TSOT-23 package. Verify that the NDIV setting and RSET value provide the necessary pulse width accuracy for the specific timing requirement.

Multivibrators Part Context

This component belongs to the LTC6993 series of silicon timing devices. It shares functional similarities with other TimerBlox parts but is distinct in its specific trigger polarity and retrigger capability. The MP grade ensures reliability in extreme thermal conditions compared to C or I grades.

Multivibrators Replacement Considerations

LTC6993MPS6-1#TRMPBF (Non-retriggerable), LTC6993MPS6-3#TRMPBF (Falling-edge, Non-retriggerable), LTC6993MPS6-4#TRMPBF (Falling-edge, Retriggerable).

Multivibrators FAQ

How is the output pulse width programmed?

The pulse width is set by the master oscillator frequency, controlled by a resistor (RSET) on the SET pin, and multiplied by an internal divider ratio (NDIV) selected via the DIV pin.

What is the difference between LTC6993-2 and LTC6993-1?

The LTC6993-2 is retriggerable, allowing the output pulse to be extended by subsequent trigger signals, whereas the LTC6993-1 ignores triggers until the current pulse completes.
