The TPS3831G33DQNR is a voltage supervisor (or reset IC) from Texas Instruments. It is designed to monitor supply voltages in microprocessor systems and provide a reset signal when the voltage drops below a certain threshold, ensuring safe operation and preventing data corruption.
The device comes in a small and compact package, specifically the 2-pin SOT-23 package. The two pins are typically assigned as follows:
1. VDD (Pin 1): This is the power supply pin where the monitored voltage is applied. The TPS3831G33DQNR monitors this voltage and triggers a reset when it falls below a pre-set threshold, which in this case, is set for 3.3V systems.
2. RESET (Pin 2): This is the output pin that provides the reset signal. It is an active-low output, meaning it will output a low signal to indicate a reset condition when the monitored voltage is below the threshold.
This IC is used to ensure that systems reset reliably under low-voltage conditions and is particularly suitable for battery-powered and low-power applications due to its low power consumption.
