The TPS3831G33DQNR is a voltage supervisor IC from Texas Instruments. It is part of the TPS3831 series, which is designed to monitor system voltages and provide a reset signal to the microprocessor when these voltages fall below a certain threshold.
This particular variant, TPS3831G33DQNR, is housed in a small 4-pin package. The pin functions typically include the following:
1. VDD: This pin is connected to the voltage that needs to be monitored. The device monitors the VDD pin for undervoltage conditions.
2. GND: The ground reference pin for the device.
3. RESET: This is the active-low reset output pin. The RESET pin is driven low when VDD falls below the specified threshold voltage, indicating an undervoltage condition. It remains low for a set delay period once VDD returns to above the threshold.
4. N/C or Other Variant Specific Pin: Often, the fourth pin can be a no-connect (N/C) or could serve a different function depending on specific package variants.
Always refer to the specific datasheet for precise pin configurations and threshold values.
