The TLV809K33DBVR is a voltage supervisor IC manufactured by Texas Instruments. It is a 3-pin device that serves the function of monitoring the supply voltage in electronic systems to ensure it stays above a defined threshold. The IC is designed to reset a microcontroller or other digital system when the monitored voltage drops below the specified threshold, in this case, 3.3V. The three pins are:
1. VDD: This is the power supply pin where the voltage to be monitored is connected.
2. GND: This pin is connected to the ground of the system.
3. RESET: This output pin is used to send a reset signal to the microcontroller or other devices being monitored. It goes low when the monitored voltage drops below the threshold and returns high when the voltage goes back above the threshold, following a delay.
This IC is used to maintain the reliability of the system by ensuring that it only operates within safe voltage levels.
