Overview of Texas Instruments TLV809L30DBVR

The Texas Instruments TLV809L30DBVR is a voltage supervisor designed to provide reliable monitoring of power supplies in digital systems. It ensures that microprocessors, microcontrollers, and other digital systems operate optimally by resetting these devices during power-up, power-down, and brown-out conditions. This product is part of the TLV809 series, known for its low power consumption and small form factor, making it an ideal choice for battery-operated and space-constrained applications.

Key Features

• Supply Voltage Monitoring: The TLV809L30DBVR supervises a 3.0V supply voltage, ensuring that the system voltage remains within acceptable thresholds for stable operation.
• Reset Timeout Delay: It features a fixed delay time of 200ms (typical), which provides a sufficient window for the system to stabilize before allowing the processor to resume operation.
• Low Power Consumption: With a quiescent current of just 9µA (typical), the device is optimized for power-sensitive applications.
• Compact Package: The device comes in a tiny SOT-23 (DBV) package, which is perfect for space-constrained designs.
• Open-Drain RESET Output: The open-drain output allows for simple interfacing with a variety of logic levels and can be wire-OR'ed to manage multiple devices.
