Product Overview: TPS3813K33QDBVRQ1

The TPS3813K33QDBVRQ1 is a high-quality, precision-supply voltage supervisor designed and manufactured by Texas Instruments. This device is engineered to monitor the system voltage in electronic applications, ensuring that the voltage levels remain within specified thresholds for reliable operation. It is particularly suitable for automotive and industrial applications where voltage accuracy and reliability are of utmost importance.

The TPS3813K33QDBVRQ1 features a fixed-sense threshold voltage of 3.3V, which makes it ideal for supervising 3.3V power supplies. Its low threshold voltage accuracy, at 1.5% over the full temperature range, provides a precise monitoring solution for systems that cannot tolerate significant voltage deviations.

One of the key attributes of this voltage supervisor is its low current consumption. With a typical quiescent current of only 9 µA, it is an energy-efficient choice for battery-powered and power-sensitive applications. This helps to extend the battery life and reduce power loss, making it an environmentally friendly option.

The TPS3813K33QDBVRQ1 comes in a compact SOT-23-6 package, which is suitable for space-constrained designs. Despite its small size, it does not compromise on performance, offering a fast response time that ensures quick system reaction to any voltage anomalies.

Furthermore, the device incorporates a manual reset input, which allows for an external signal to trigger a system reset. This feature provides additional control to system designers and can be used to implement custom reset functionalities. The reset output is active low and is of the open-drain type, which allows for easy interfacing with other logic components.

For automotive applications, the TPS3813K33QDBVRQ1 is qualified for operation over a wide temperature range of -40°C to +125°C, ensuring consistent performance even under harsh environmental conditions. Additionally, it is AEC-Q100 qualified, highlighting its compliance with stringent automotive industry standards for reliability and quality.

In summary, the TPS3813K33QDBVRQ1 from Texas Instruments is a robust, precise, and energy-efficient voltage supervisor that offers a comprehensive solution for voltage monitoring in automotive and industrial systems. Its compact size, low power consumption, and high accuracy make it a top choice for system designers looking for a dependable voltage supervision component.
