LTC6993IDCB-4#TRPBF

Multivibrators Overview

The Analog Devices LTC6993IDCB-4#TRPBF is a monostable multivibrator (one-shot) pulse generator in the TimerBlox family. It generates output pulses with widths ranging from 1µs to 33.55 seconds, programmed via an external resistor (RSET) and an internal divider (NDIV). This specific variant features falling-edge trigger sensitivity and retrigger capability. It operates on a single supply voltage between 2.25V and 5.5V, drawing as low as 55µA at 2.25V. The device is housed in a 6-lead DFN package and is rated for industrial temperatures from –40°C to 85°C.

Multivibrators Feature Summary

• Programmable pulse width generation using a single external resistor and internal clock divider settings.
• Falling-edge trigger input with retrigger functionality to extend pulse duration upon subsequent triggers.
• Configurable output polarity via DIV pin voltage, allowing positive or negative pulse generation.
• Low power consumption with fast recovery time and CMOS-compatible output driver.

Multivibrators Applications

• Watchdog timer circuits requiring reliable timeout detection.
• Missing pulse detection systems for monitoring signal integrity.
• Envelope detection in communication receivers.
• Frequency discriminators for signal analysis.

Multivibrators Procurement Notes

Verify the exact part number suffix #TRPBF confirms tape and reel packaging. Confirm the 'I' grade indicates the –40°C to 85°C operating range. Ensure the DCB package matches the PCB footprint. Check for automotive qualified variants if required by application standards.

Multivibrators Selection Notes

Select this variant when falling-edge triggering and retriggering are required. Choose based on the desired temperature range; the 'I' grade suits industrial environments. Consider the NDIV setting needed for the target pulse width. Verify supply voltage compatibility within the 2.25V to 5.5V range.

Multivibrators Part Context

This component belongs to the LTC6993 TimerBlox family of silicon timing devices. It shares core architecture with other variants differing primarily in trigger polarity and retrigger capability. The IDCB-4 designation specifies the industrial temperature grade, DFN-6 package, and specific logic configuration for falling-edge retriggerable operation.

Multivibrators Replacement Considerations

LTC6993HDCB-4#TRPBF offers the same logic but extended high-temperature range. LTC6993IDCB-2#TRPBF provides rising-edge trigger instead of falling-edge. Other family members like LTC6992 differ in function as PWM controllers rather than one-shots.
