LTC6993HDCB-2#TRPBF

Multivibrators Overview

The LTC6993HDCB-2#TRPBF is a monostable multivibrator from the TimerBlox family, housed in a 6-lead DFN package. It operates on a single supply voltage ranging from 2.25V to 5.5V with an operating temperature range of -40°C to 125°C. The device generates programmable output pulses between 1µs and 33.6 seconds using a master oscillator set by RSET and a divider NDIV. It features rising-edge triggering with retrigger capability, CMOS output drivers sourcing/sinking up to 20mA, and low supply current consumption.

Multivibrators Feature Summary

• Retriggerable monostable operation responding to rising-edge trigger signals
• Programmable pulse width via external resistor and internal clock divider settings
• Configurable output polarity through DIV pin voltage selection
• CMOS output stage capable of driving moderate loads directly

Multivibrators Applications

• Watchdog timer circuits requiring periodic reset signals
• Missing pulse detection systems for monitoring signal integrity
• Envelope detection in modulated carrier processing
• Timing control in high vibration or acceleration environments

Multivibrators Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the HDCB designation corresponds to the industrial/high-temperature grade DFN package variant. Ensure compatibility with existing board layouts regarding the 2mm x 3mm footprint and exposed pad thermal connection requirements specified in the datasheet.

Multivibrators Selection Notes

Select this variant for applications requiring retriggerable behavior triggered by rising edges. The H-grade ensures reliable performance across the extended -40°C to 125°C temperature range. Consider the DFN package for space-constrained designs where thermal dissipation through the exposed pad is manageable. Verify that the required pulse width accuracy meets the specifications for the chosen NDIV setting.

Multivibrators Part Context

This component belongs to the LTC6993 series of silicon timing devices, designed as versatile one-shot pulse generators. The series includes variants with different trigger polarities and retrigger capabilities. The HDCB suffix identifies the specific temperature grade and plastic DFN package configuration within the broader TimerBlox product line.

Multivibrators Replacement Considerations

LTC6993IDCB-2#TRPBF offers identical functionality but with a commercial temperature range of -40°C to 85°C instead of the extended range.
