The TPS3820-33QDBVRQ1 is a voltage supervisor IC manufactured by Texas Instruments. It comes in a 5-pin SOT-23 package. The pin functions are as follows:
1. VDD: This pin is connected to the supply voltage that the IC is monitoring.
2. GND: This pin is the ground connection for the IC.
3. RESET: This active-low output pin indicates a reset condition. It goes low when VDD falls below the threshold voltage and remains low for a fixed delay time after VDD returns above the threshold.
4. MR (Manual Reset): This active-low input pin allows for an external reset signal. Pulling this pin low forces a reset.
5. WDI (Watchdog Input): This pin is used for the watchdog function. It must be toggled within a specified timeout period to prevent the RESET pin from being asserted.
The TPS3820-33QDBVRQ1 is primarily used for monitoring the supply voltage and ensuring a microcontroller resets when necessary, thus providing reliable system operation.
