The TPS3838K33QDBVRQ1 is a high-precision voltage supervisor designed by Texas Instruments to monitor power supplies in digital systems. It is specifically engineered to ensure that microprocessors (µPs), microcontrollers (MCUs), and other voltage-sensitive components operate within their specified voltage ranges.

Key Features:

• Voltage Threshold: The device features a fixed-sense threshold voltage of 3.3V, which is ideal for monitoring 3.3V power supplies.
• Low Power Consumption: With a typical supply current of only 1.5 µA, the TPS3838K33QDBVRQ1 is optimized for battery-powered and low-power applications.
• High Accuracy: It offers a high threshold accuracy of ±1.5%, which provides reliable monitoring and enhances system stability.
• Reset Time Delay: The built-in, programmable time delay ensures that the system has stabilized before the processor is allowed to operate, preventing system errors during power-up or power-down events.
• Temperature Range: The device operates over a wide temperature range, making it suitable for automotive and industrial applications that require robust performance.
• Package Type: The TPS3838K33QDBVRQ1 comes in a compact SOT-23-3 package, which is space-efficient for design in tight PCB layouts.
