TPS3838L30QDBVRQ1 - Texas Instruments Voltage Supervisor

The TPS3838L30QDBVRQ1 is a high-precision voltage supervisor designed by Texas Instruments to ensure reliable operation of microprocessors, microcontrollers, and other voltage-sensitive devices. This component is particularly engineered to monitor the supply voltage and maintain system integrity by asserting a reset signal whenever the monitored voltage drops below a predefined threshold. The TPS3838L30QDBVRQ1 is an essential component for automotive and industrial applications where voltage accuracy and stability are critical for safety and performance.

Featuring a fixed-sense threshold voltage of 3.0V, this voltage supervisor is tailored for systems that operate within a specific voltage range, providing an active-low reset output. The reset delay time is programmable by an external capacitor, offering designers flexibility in how they manage system power-up and brownout conditions. The low quiescent current of 1.5 µA (typical) ensures minimal power consumption during operation, making it suitable for power-sensitive applications.

Encased in a compact SOT-23-6 package, the TPS3838L30QDBVRQ1 is designed for space-constrained applications, providing a robust voltage monitoring solution without occupying significant board space. This package is also characterized for automotive applications, complying with the AEC-Q100 Grade 1 standard, which means it can operate in the extended temperature range of -40°C to +125°C, ensuring reliability in harsh environments.
