LTC6993HDCB-2#TRMPBF

Multivibrators Overview

The LTC6993HDCB-2#TRMPBF is a monostable multivibrator from the TimerBlox family, housed in a 6-lead DFN package. It generates programmable output pulses ranging from 1µs to 33.6 seconds via an internal master oscillator and divider. The device features rising-edge triggering with retrigger capability, allowing pulse extension by subsequent triggers. It operates on a single supply voltage between 2.25V and 5.5V, drawing as low as 70µA at specific settings. The component supports configurable positive or negative output polarities and includes fast recovery times suitable for high-frequency applications.

Multivibrators Feature Summary

• Retriggerable monostable operation initiated by rising-edge trigger signals
• Programmable pulse width determined by external resistor and internal divider settings
• Configurable output polarity via DIV pin voltage control
• Low power consumption with fast start-up and recovery characteristics

Multivibrators Applications

• Watchdog timer circuits requiring periodic reset monitoring
• Missing pulse detection systems for signal integrity verification
• Envelope detectors for amplitude modulation analysis
• Frequency discriminators utilizing pulse width variation

Multivibrators Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel mini packaging when sourcing. Confirm the HDCB designation corresponds to the DFN-6 package variant required for your layout. Ensure the H grade meets the -40°C to 125°C operating temperature range needed for your environment. Cross-reference the full part number against official Analog Devices documentation to confirm availability status and lead times directly with authorized distributors.

Multivibrators Selection Notes

Select this variant specifically for its retriggerable functionality triggered by rising edges. The H grade ensures operation across the extended industrial temperature range of -40°C to 125°C. The DFN package offers a compact footprint suitable for space-constrained designs. Consider the DIV pin configuration requirements for setting the desired divider ratio and output polarity before finalizing the schematic.

Multivibrators Part Context

This component belongs to the LTC6993 series of TimerBlox silicon timing devices. It shares architectural similarities with non-retriggerable variants like the LTC6993-1 and falling-edge versions like the LTC6993-3. The series provides versatile pulse generation capabilities using minimal external components. All variants utilize the same core oscillator architecture but differ in trigger logic and retriggering behavior.

Multivibrators Replacement Considerations

LTC6993IDCB-2#TRMPBF serves as a direct replacement within the commercial temperature range (-40°C to 85°C). For automotive applications, consider the AEC-Q100 qualified LTC6993HS6-2#WTRMPBF in the TSOT-23 package. Verify that any substitute maintains the retriggerable rising-edge trigger characteristic and compatible DFN or SOT-23 form factor.
