Présentation

Description

The TLV803EB26RDBZR is a voltage supervisor or reset IC designed to monitor the voltage levels in electronic circuits. It specifically targets applications requiring precise voltage monitoring and reset functionalities to ensure system reliability and prevent malfunction. The device typically operates by tracking the supply voltage and issuing a reset signal when the voltage falls below a predefined threshold. This helps in protecting microcontrollers and other digital systems from operating under insufficient voltage conditions, which can lead to erratic behavior.
Key features of the TLV803EB26RDBZR include low power consumption, high accuracy in voltage detection, and a compact package, making it suitable for portable and space-constrained applications. It is often used in consumer electronics, automotive systems, and industrial applications where maintaining proper voltage levels is crucial. The IC generally offers a fixed reset threshold voltage, in this case, 2.6 volts, ensuring that devices are reset at the correct voltage level. Additionally, it comes with a push-pull output for reset, providing a straightforward integration into various circuit designs.

Features

The TLV803EB26RDBZR is a low-power voltage supervisor with specific features that ensure reliable system performance. Key features include:
1. Reset Threshold: It is designed to monitor 2.6V voltage levels, providing a precision reset signal when the monitored voltage drops below this threshold.
2. Reset Delay: The device offers a fixed reset delay, ensuring that the system remains in reset for an adequate time after power stabilization.
3. Low Power Consumption: Its design emphasizes low power usage, making it suitable for battery-powered and energy-efficient applications.
4. Push-Pull Output: The TLV803EB26RDBZR features a push-pull output configuration, allowing for direct connection to microcontroller reset inputs without additional components.
5. Compact Package: Available in a small SOT-23 package, it saves space on the PCB, making it ideal for compact applications.
6. Operating Temperature Range: It operates effectively over a wide temperature range, ensuring reliability in various environmental conditions.
These features make the TLV803EB26RDBZR an excellent choice for applications requiring precise voltage monitoring and efficient power management.

Pinout

The TLV803EB26RDBZR is a voltage supervisor with a 3-pin configuration. It is part of the TLV803 series designed for monitoring supply voltages in electronic systems. The device typically includes the following pins:
1. VDD (Supply Voltage Input): This pin is connected to the voltage that needs to be monitored. The TLV803EB26RDBZR monitors this voltage level to ensure it remains above a specified threshold.
2. GND (Ground): This pin serves as the common ground reference for the device.
3. RESET (Reset Output): This pin is an active-low output that goes low when the monitored voltage falls below the specified threshold (in this case, 2.6V). Once the voltage returns to acceptable levels, the RESET output is released after a certain delay, thus allowing the system to return to normal operation.
The TLV803EB26RDBZR is used to ensure that the microcontroller or other digital circuits receive a stable and sufficient voltage, preventing malfunction during undervoltage conditions.
