LTC6994HS6-2#WTRPBF

Overview

The LTC6994HS6-2#WTRPBF is an automotive-grade programmable delay block from the TimerBlox family, housed in a 6-lead TSOT-23 package. It provides a delay range of 1µs to 33.6 seconds, configured via a single RSET resistor and an internal divider (NDIV) selectable from eight settings. The device operates on a single supply voltage between 2.25V and 5.5V with a typical supply current of 70µA at 10µs delay. It features a CMOS output driver capable of sourcing or sinking 20mA and supports dynamic delay adjustment through a control voltage.

Feature Summary

• Configurable delay functionality for rising edges, falling edges, or both transitions
• Dynamic delay time adjustment capability via external control voltage
• Automotive qualification compliant with AEC-Q100 standards
• Low power consumption suitable for battery-operated applications

Applications

• Noise discriminators and pulse qualifiers
• Switch debouncing circuits
• Delay matching in timing systems
• Operation in high vibration and high acceleration environments

Procurement Notes

Verify the specific suffix #WTRPBF indicates tape and reel packaging for the HS6 automotive grade variant. Confirm that the component meets AEC-Q100 requirements if used in automotive designs. Check for any specific automotive reliability reports required by the manufacturer. Ensure the ordering information matches the desired temperature range and package type.

Selection Notes

Select the LTC6994HS6-2 variant when both rising and falling edge delays are required, along with optional output inversion. Choose this part over the -1 version if simultaneous edge handling is necessary. Consider the HS6 grade for extended industrial temperature ranges up to 125°C. Verify that the 8-tap divider resolution meets the precision requirements of the application.

Part Context

This component belongs to the Analog Devices TimerBlox family of silicon timing devices. It shares architectural similarities with other TimerBlox parts like the LTC6990 but focuses specifically on precise delay generation rather than frequency oscillation. The HS6 designation identifies it as an automotive-grade product in a thin SOT-23 package.

Replacement Considerations

Direct substitutes include other Automotive Grade variants within the LTC6994 family such as LTC6994IS6-2#WTRPBF for commercial temperature ranges. Non-automotive equivalents like LTC6994HS6-2#TRMPBF may be considered if automotive qualification is not required.
