Product Overview: TPS3831G33DQNR by Texas Instruments

The TPS3831G33DQNR is a state-of-the-art voltage supervisor integrated circuit (IC) designed and manufactured by Texas Instruments (TI), a leader in semiconductor solutions. This compact and efficient IC is engineered to ensure reliable system monitoring, specifically tailored for applications that require precise voltage supervision to safeguard against undervoltage conditions.

At the heart of the TPS3831G33DQNR is a highly accurate supervisory circuit that monitors the supply voltage of digital systems. It provides a fixed-sense threshold voltage of 3.3V, which is ideal for a wide range of electronic devices. When the monitored voltage falls below the 3.3V threshold, the output is driven low, which can be used to trigger a reset in microcontrollers and other digital systems, ensuring proper operation and preventing data corruption or system failures.

The device comes in a compact 6-pin X2SON package, making it suitable for space-constrained applications. It boasts a low quiescent current of just 1.5 µA (typical), which is particularly beneficial for portable and battery-powered devices, as it helps to extend battery life by minimizing power consumption when the device is in standby mode.

Additional features of the TPS3831G33DQNR include a manual reset input, which allows for an external signal to initiate a system reset. This is a critical feature for systems that require user-initiated resets or for those that need to implement a reset sequence from another part of the system. Furthermore, the device has a power-on reset delay which provides a fixed delay time after the supply voltage has risen above the threshold level, ensuring the system has adequate time to stabilize before normal operation commences.

Texas Instruments' TPS3831G33DQNR is designed for robust operation, with a wide operating temperature range of -40°C to +125°C, making it suitable for industrial and automotive applications. Whether it's used in computing systems, portable electronics, or complex automotive electronics, this voltage supervisor IC delivers the reliability and performance that engineers have come to expect from Texas Instruments.
