The TPS3809K33DBVT from Texas Instruments is a supervisory circuit providing essential initialization and timing supervision for processor-based systems. This device monitors a single supply voltage and asserts a reset signal when the voltage drops below a specific threshold. The reset signal remains active for a minimum of 120ms after the supply voltage has risen above the threshold, ensuring proper system reset.
Key electrical characteristics include a typical threshold voltage of 2.93V with an accuracy of 2.2% and a low typical supply current of 0.009mA. The reset output is active-low and push-pull, and the device offers a typical reset time delay of 200ms. It is designed to operate within an ambient temperature range of -40°C to 85°C.
Packaged in a compact SOT-23-3 surface-mount package, the TPS3809K33DBVT is suitable for space-constrained applications. Its features, such as ease-of-use and manual reset capability, make it a versatile component for various embedded systems requiring reliable power-on reset functionality.
