LTC6994HS6-1#TRPBF

Overview

The LTC6994HS6-1#TRPBF is a programmable delay block from the TimerBlox family, housed in a 6-lead Plastic TSOT-23 package. It operates on a single supply voltage ranging from 2.25V to 5.5V and supports an operating temperature range of -40°C to 125°C. The device provides a delay range from 1µs to 33.6 seconds, programmed via a single resistor (RSET) connected to the SET pin and a divider code (NDIV) selected via the DIV pin. The LTC6994-1 variant delays either the rising or falling edge based on configuration. Supply current is typically 70µA at a 10µs delay. The output driver can source or sink up to 20mA.

Feature Summary

• Configurable delay functionality allowing selection between delaying rising edges or falling edges for the LTC6994-1 variant.
• Single-resistor programming capability using an external RSET component to set the master oscillator time base.
• Internal programmable frequency divider with eight selectable settings to extend the total delay duration.
• Automotive-grade qualification ensuring reliability under high vibration and acceleration conditions.

Applications

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

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm that the HS6 designation corresponds to the automotive-grade temperature range and TSOT-23 package type required for your design. Ensure compatibility with the manufacturer's automotive quality standards before finalizing procurement specifications.

Selection Notes

Select the LTC6994HS6-1#TRPBF when automotive qualification and wide temperature operation are required. Choose this part over commercial variants if the application demands reliability in harsh environments. Verify that the delay requirements fit within the 1µs to 33.6s range and that the single-edge delay feature of the -1 variant meets the circuit logic needs.

Part Context

This component belongs to the Analog Devices TimerBlox family of silicon timing devices. It shares functional similarities with other parts in the series but is distinguished by its automotive grade rating and specific package configuration. The HS6 suffix denotes the high-temperature performance and thin SOT-23 form factor suitable for space-constrained designs.
