Overview of Texas Instruments TLV803EC29DBZR Voltage Supervisor

The Texas Instruments TLV803EC29DBZR is a precision voltage supervisor designed to ensure reliable operation of microprocessors, microcontrollers, and other voltage-sensitive devices. This component is crucial for systems that require a stable and accurate monitoring of the supply voltage to prevent data corruption, erratic behavior, or damage to the electronic circuitry during power fluctuations, brownouts, or power-up conditions.

Key Features

• Supply Voltage Monitoring: The TLV803EC29DBZR actively monitors the supply voltage (V_CC) and keeps a watchful eye on the system's power integrity. It has a fixed-sense threshold voltage of 2.93V, which is suitable for 3V to 3.3V powered systems.
• Reset Output: Upon detecting an out-of-tolerance voltage condition, it asserts a reset signal that remains active until the V_CC returns to an acceptable level, ensuring the system has adequate time to return to a stable state before resuming operation.
• Low Power Consumption: With its low quiescent current, this device is an excellent choice for power-sensitive applications, minimizing the impact on the overall power budget of the system.
• High Accuracy: The voltage threshold accuracy is ±1.5%, providing precise monitoring which is essential for reliable system operation.
• Small Form Factor: The compact SOT-23 package is space-efficient, making it ideal for use in space-constrained applications.
