LTC6993HS6-1#WTRMPBF

Multivibrators Overview

The LTC6993HS6-1#WTRMPBF is an automotive-grade monostable multivibrator from the TimerBlox family, housed in a 6-lead TSOT-23 package. It generates programmable output pulses ranging from 1µs to 33.6 seconds via a single external resistor and internal divider settings. The device operates on a single supply voltage between 2.25V and 5.5V with a typical idle current of 70µA at 10µs pulse width. It features rising-edge triggering without retrigger capability, CMOS outputs sourcing/sinking 20mA, and an operating temperature range of -40°C to 125°C.

Multivibrators Feature Summary

• Generates precise one-shot pulses with widths programmable from 1µs to 33.6 seconds using a single resistor and internal clock divider.
• Configurable for positive or negative output polarity and supports dynamic pulse width adjustment via control voltage.
• Includes hysteresis on the trigger input to accommodate slow-rising signals and provides fast recovery time for subsequent triggers.
• Automotive qualified (AEC-Q100) with robust performance in high vibration and acceleration environments.

Multivibrators Applications

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

Multivibrators Procurement Notes

Verify the specific suffix #WTRMPBF confirms automotive qualification and tape-and-reel packaging. Confirm the HS6 designation matches the required -40°C to 125°C temperature grade and TSOT-23 package. Ensure compatibility with existing BOM specifications regarding lead-free finish and RoHS compliance before finalizing orders.

Multivibrators Selection Notes

Select this variant for applications requiring rising-edge triggered non-retriggerable operation within the automotive temperature range. Compare against LTC6993-2 if retrigger functionality is needed, or LTC6993-3/4 if falling-edge sensitivity is preferred. Consider the DFN package option if board space constraints differ from the TSOT-23 footprint requirements.

Multivibrators Part Context

This component belongs to the Analog Devices TimerBlox family of silicon timing devices, designed for versatile pulse generation and timing control. The LTC6993 series integrates master oscillators and programmable dividers to simplify timing circuit design by reducing the need for multiple discrete components.

Multivibrators FAQ

How is the output pulse polarity determined?

The output polarity is controlled by the DIVCODE setting accessed via the DIV pin. A POL bit of 0 produces a positive pulse, while a POL bit of 1 produces a negative pulse.

What is the trigger behavior for the LTC6993-1 version?

The LTC6993-1 is sensitive to rising-edge triggers and is not retriggerable. Additional trigger signals are ignored until the current output pulse terminates.
