LTC6994MPS6-1#TRPBF

Overview

The LTC6994MPS6-1#TRPBF is a programmable delay block from the TimerBlox family, designed for single-supply operation between 2.25V and 5.5V. It provides a delay range of 1µs to 33.6 seconds, determined by an internal master oscillator and a programmable divider (NDIV) with eight settings from 1 to 2^21. The device features a CMOS output driver capable of sourcing and sinking 20mA. It operates within an extended temperature range of –55°C to 125°C and is qualified for automotive applications under AEC-Q100 standards.

Feature Summary

• Configurable edge-delay functionality allowing selection of rising or falling transition delays via the DIV pin polarity bit.
• Noise discrimination capability through pulse qualification, filtering out input signals shorter than the programmed delay duration.
• Dynamic delay adjustment support via a separate control voltage on the SET pin for real-time timing modifications.

Applications

• Noise discriminators and pulse qualifiers in signal conditioning circuits
• Switch debouncing mechanisms for mechanical contact inputs
• Delay matching applications requiring precise timing alignment

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm that the MPS6 designation corresponds to the –55°C to 125°C operating temperature grade required for your environment. Ensure compatibility with AEC-Q100 automotive reliability standards if applicable to your design specifications.

Selection Notes

Select this model over standard industrial grades when operation below –40°C or above 85°C is required. The MPS6 variant ensures guaranteed performance across the full –55°C to 125°C range. Verify that the TSOT-23 package fits your PCB footprint constraints compared to DFN alternatives.

Part Context

This component belongs to the Analog Devices TimerBlox family of silicon timing devices. It shares functional similarities with other LTC6994 variants but is distinguished by its military/automotive temperature grade and specific packaging configuration. It serves as a versatile alternative to discrete RC delay networks.

Replacement Considerations

LTC6994MPS6-2#TRPBF offers identical electrical characteristics but delays both rising and falling edges with optional inversion. LTC6994HS6-1#TRPBF provides similar functionality but is rated for –40°C to 125°C rather than the wider –55°C to 125°C range of the MPS6 version.
