Linear Technology LTC6994IS6-1 TimerBlox Delay Block IC

The LTC6994IS6-1 is a versatile delay block integrated circuit, part of Linear Technology's TimerBlox series, which is designed to provide users with a simple, accurate, and programmable delay of events in their electronic applications. This compact, monolithic device is capable of producing a fixed delay from microseconds to seconds, making it an ideal choice for a wide range of timing applications.

Constructed with advanced silicon technology, the LTC6994IS6-1 is housed in a compact SOT-23 package, specifically the 6-lead SOT-23 package, which is suitable for space-constrained applications. This delay block IC operates over a single supply voltage range of 2.25V to 5.5V, ensuring compatibility with a variety of low-voltage systems.

One of the key features of the LTC6994IS6-1 is its ease of use. The delay time is programmed with a single external resistor, providing users with the flexibility to set the desired time delay without the need for complex programming. The delay range can be set to one of four possible ranges by configuring the onboard DIV input, and the delay can be fine-tuned within that range via the external resistor.

The LTC6994IS6-1 boasts precision delay accuracy, with a maximum cumulative delay error of only 3.5% or 500µs, whichever is greater. This high level of accuracy is maintained over the full operating temperature range, power supply variations, and from unit to unit. Furthermore, the output stage of the LTC6994IS6-1 can source or sink up to 20mA, which means it can directly drive optoisolators or small relays without additional buffering.

Additional features of the LTC6994IS6-1 include a fast start-up time, low power consumption, and a shutdown feature that reduces current to 0.1µA, making it suitable for battery-powered and portable applications. Its robustness is further enhanced by its wide operating temperature range of -40°C to 125°C.

In summary, the LTC6994IS6-1 from Linear Technology is a highly reliable and easy-to-use delay block IC that provides precise and programmable timing solutions for a vast array of electronic systems.
