LTC6993MPS6-1#TRMPBF

Multivibrators Overview

The LTC6993MPS6-1#TRMPBF is a monostable multivibrator from the TimerBlox family, packaged in a 6-lead Plastic TSOT-23. It operates on a single supply voltage ranging from 2.25V to 5.5V with a maximum supply current of 200µA. The device generates output pulses with widths programmable from 1µs to 33.6 seconds using an external resistor and internal divider settings. It features a rising-edge trigger input without retrigger capability, CMOS output drivers capable of sourcing or sinking up to 20mA, and an operating temperature range of –55°C to +125°C.

Multivibrators Feature Summary

• Generates programmable output pulses ranging from 1µs to 33.6 seconds via a master oscillator and internal clock divider.
• Configured with a single external resistor for time base setting and optional resistors for divider selection.
• Supports dynamic pulse width adjustment through a separate control voltage input.
• Provides fast recovery time and configurable positive or negative output pulse polarity.

Multivibrators Applications

• Watchdog timer circuits
• Frequency discriminators
• Missing pulse detection systems
• Envelope detectors
• Portable and battery-powered equipment

Multivibrators Procurement Notes

Verify the specific suffix MPS6 indicates the military/extended grade variant with –55°C to +125°C operation. Confirm the #TRMPBF suffix corresponds to the mini tape and reel packaging format. Ensure compatibility with the required SMD/SMT installation style and check for any automotive qualification requirements if applicable to the target system.

Multivibrators Selection Notes

Select this component when a non-retriggerable, rising-edge triggered monostable pulse generator is required. Choose this part over other variants if the application demands extended temperature performance down to –55°C. Consider the available divider settings and output drive strength when designing the load interface.

Multivibrators Part Context

This device belongs to the Analog Devices TimerBlox family of versatile silicon timing devices. It is specifically the LTC6993-1 variant, characterized by its rising-edge trigger sensitivity and lack of retrigger functionality. The MPS6 package designation identifies it as the low-profile 6-lead Plastic TSOT-23 form factor suitable for space-constrained designs.

Multivibrators FAQ

How is the output pulse width programmed?

The pulse width is determined by the master oscillator frequency set by an external resistor (RSET) and an internal clock divider (NDIV) selected via the DIV pin voltage.

What is the trigger behavior of the LTC6993-1?

The LTC6993-1 is sensitive to rising-edge triggers and is not retriggerable; subsequent triggers are ignored until the current pulse terminates.
