LTC6994MPS6-2#TRMPBF

Overview

The LTC6994MPS6-2#TRMPBF 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 –55°C to 125°C. The device provides a delay range from 1µs to 33.6 seconds, configured via a single resistor (RSET) and a programmable divider (NDIV). It features a CMOS output driver capable of sourcing and sinking 20mA, with a typical supply current of 70µA at a 10µs delay.

Feature Summary

• Configurable delay functionality for rising or falling edges using a single external resistor
• Dynamic adjustment capability through a separate control voltage input
• Automotive-grade qualification supporting high vibration and acceleration environments

Applications

• Noise discriminators and pulse qualifiers
• Switch debouncing circuits
• Delay matching applications
• Portable and battery-powered equipment

Procurement Notes

Verify the specific suffix #TRMPBF indicates the mini tape and reel packaging format. Confirm the MPS6 designation corresponds to the specified –55°C to 125°C military temperature grade and TSOT-23 package type. Ensure compatibility with automotive reliability requirements if applicable.

Selection Notes

Select this model for applications requiring extended low-temperature performance down to –55°C. The -2 variant delays both rising and falling transitions, unlike the -1 version. Configuration requires only one to three resistors to set the time base and divider ratio.

Part Context

This component belongs to the Analog Devices TimerBlox family of versatile silicon timing devices. It serves as a programmable delay block designed for precise timing control in compact surface-mount packages. The device integrates an internal master oscillator and clock divider to achieve wide-ranging delay capabilities.
