LTC6993IDCB-4#TRMPBF

Multivibrators Overview

The LTC6993IDCB-4#TRMPBF is a monostable multivibrator from the TimerBlox family, operating on a single supply voltage ranging from 2.25V to 5.5V. It generates programmable output pulses with widths between 1µs and 33.6 seconds. The pulse duration is set by an external resistor (RSET) connected to the SET pin and an internal divider ratio (NDIV) selected via the DIV pin. This specific variant features falling-edge trigger sensitivity and retrigger capability. It operates within an industrial temperature range of –40°C to 85°C and is housed in a 6-lead 2mm × 3mm Plastic DFN package.

Multivibrators Feature Summary

• Configurable for falling-edge triggering with retrigger functionality to extend pulse width
• Programmable pulse width determined by external resistor and internal clock divider settings
• Capable of generating positive or negative output pulses via polarity control bit
• Low power consumption with fast recovery time suitable for battery-powered applications

Multivibrators Applications

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

Multivibrators Procurement Notes

Verify that the ordering suffix #TRMPBF corresponds to the Tape and Reel (Mini) packaging format as specified in the manufacturer's order information table. Confirm the device grade 'I' matches the required –40°C to 85°C operating temperature range for your application environment. Ensure the DCB package type aligns with your PCB footprint design constraints.

Multivibrators Selection Notes

Select this component when falling-edge trigger activation is required alongside retrigger capability. The IDCB-4 designation specifically indicates the industrial temperature grade and the 6-lead DFN package form factor. Consider the NDIV setting requirements for desired pulse width ranges and ensure the RSET resistor tolerance meets accuracy specifications for the target timing precision.

Multivibrators Part Context

This part belongs to the LTC6993-1/LTC6993-2 and LTC6993-3/LTC6993-4 families of TimerBlox silicon timing devices. The -4 suffix denotes the version with falling-edge trigger input and retrigger support. It shares core architecture with other variants differing primarily in trigger polarity and retriggerability options while maintaining identical electrical characteristics and package options.

Multivibrators Replacement Considerations

LTC6993HDCB-4#TRMPBF offers the same functional specifications but supports an extended temperature range up to 125°C.
