Overview of Texas Instruments TLV803EA29RDBZR

The Texas Instruments TLV803EA29RDBZR is a precision voltage supervisor designed to maintain system integrity by monitoring the supply voltage of digital systems. This device is an essential component for applications requiring high reliability and operational stability. It is particularly suitable for microprocessor, microcontroller, and other digital system's voltage monitoring needs.

Key Features

• Voltage Threshold: The TLV803EA29RDBZR has a fixed-sense threshold voltage of 2.93V, which is ideal for 3V systems. This precise threshold ensures that the system operates within its intended voltage range.
• Reset Time Delay: It offers a built-in delay feature, providing a reset time delay of 200 ms (typical), which helps prevent nuisance resets during transient conditions.
• Low Current Consumption: With a typical supply current of just 3.5 µA, this device is energy-efficient, making it an excellent choice for battery-powered applications.
• Output: The supervisor provides an active-low, open-drain RESET output, which remains asserted until the monitored voltage rises above the threshold, plus the hysteresis, ensuring a reliable startup.
• Temperature Range: It operates over a wide temperature range of -40°C to +125°C, making it versatile for various environments and applications.
• Package: The device comes in a compact, surface-mount, 3-pin SOT-23 package, which allows for space-saving PCB designs.
