TLV803MDBZT

The TLV803MDBZT is a voltage supervisor integrated circuit (IC) manufactured by Texas Instruments. It is designed to monitor power supply voltages and provide a reset signal to microcontrollers and other digital devices when the supply voltage falls below a specified threshold. This is crucial for ensuring reliable operation in electronic systems, particularly in battery-powered applications or systems that require a stable power supply.

Key Features:

1. Voltage Monitoring: The TLV803MDBZT can monitor supply voltages and detect when they drop below a predetermined threshold. This helps prevent erratic behavior in digital circuits due to insufficient voltage levels.

2. Reset Output: The IC provides a reset output signal that can be used to reset microcontrollers or other digital devices when the monitored voltage falls below the threshold. This output is typically active low, meaning it goes low when a reset condition is triggered.

3. Adjustable Threshold: The device allows for adjustable voltage thresholds, enabling designers to set the reset point according to the specific requirements of their application.

4. Low Power Consumption: The TLV803MDBZT is designed for low power operation, making it suitable for battery-powered applications where energy efficiency is critical.

5. Fast Response Time: The IC features a fast response time to voltage changes, ensuring that the reset signal is generated quickly when the supply voltage drops.

6. Temperature Range: It operates over a wide temperature range, making it suitable for various environmental conditions.

7. Compact Package: The TLV803MDBZT is available in a small, surface-mount package (SOT-23), which is ideal for space-constrained applications.

Applications:

• Microcontroller Reset: Used in microcontroller-based systems to ensure that the microcontroller starts in a known state after power-up or when the supply voltage drops.
• Battery-Powered Devices: Ideal for portable electronics where monitoring battery voltage is essential for reliable operation.
• Consumer Electronics: Commonly found in devices like smartphones, tablets, and other consumer electronics that require stable power management.
• Industrial Equipment: Used in industrial control systems to ensure that equipment operates reliably under varying power conditions.

Electrical Characteristics:

• Supply Voltage Range: Typically operates within a specified range (e.g., 1.5V to 5.5V).
• Reset Threshold Voltage: The reset threshold can be set to various levels, depending on the specific model and configuration.
• Output Drive Capability: The reset output can typically drive a certain amount of current, allowing it to interface directly with other components.

In summary, the TLV803MDBZT from Texas Instruments is a versatile and reliable voltage supervisor IC that plays a critical role in ensuring the stability and reliability of electronic systems by monitoring supply voltages and providing reset signals when necessary. Its low power consumption, fast response time, and compact design make it an excellent choice for a wide range of applications.
