TLV803RDBZR

The TLV803RDBZR is a voltage supervisor device from Texas Instruments, designed to monitor and ensure the reliability of power supplies in electronic systems. This component is particularly used to monitor the supply voltage and provide a reset signal to a microcontroller or processor if the voltage drops below a preset threshold. This is crucial in preventing malfunctions or unexpected behaviors in electronic circuits due to under-voltage conditions.
Key features of the TLV803RDBZR include low power consumption, a precision voltage threshold, and a push-pull active-low reset output. It operates over a wide supply voltage range and is available in a small SOT-23 (DBZ) package, making it suitable for space-constrained applications.
The device is commonly used in applications such as computers, servers, consumer electronics, and automotive systems, where maintaining stable operation is critical. Its simplicity and efficiency make it ideal for use in embedded systems that require constant monitoring and quick response to supply voltage drops.

The TLV803RDBZR is a voltage supervisor with several key features designed for monitoring supply voltages in electronic systems. It offers a low supply current, typically consuming only about 2.0 μA, which makes it ideal for battery-powered applications. The device provides a precise reset threshold voltage with an accuracy of ±1.5%, ensuring reliable operation and protection of microcontrollers and other digital circuits from under-voltage conditions.
This supervisor has an active-low reset output which is an open-drain configuration, allowing it to interface with a variety of logic levels. The reset output remains asserted for a fixed delay time after the monitored voltage exceeds the threshold, providing a 200 ms reset delay to ensure stability before the system resumes operation.
The TLV803RDBZR is available in a compact SOT-23 package, which is suitable for space-constrained applications. It operates over a wide temperature range from -40°C to +85°C, ensuring robustness in various environmental conditions. Overall, it is a cost-effective and efficient choice for voltage monitoring in a wide range of consumer electronics, computing, and industrial applications.

The TLV803RDBZR comes in a SOT-23-3 package type. SOT-23-3 is a small outline transistor package with three terminals, commonly used for surface-mount applications due to its compact size and convenience in automated assembly processes.
