Detailed Pin Configuration

The TCM809JVLB713 IC has a SOT-23-3 package with the following pin configuration:

1. VDD - Supply Voltage Input
2. GND - Ground
3. RESET - Active-Low Reset Output

Functional Features

• Monitors the supply voltage and asserts a reset signal when it falls below the specified threshold.
• Provides a precision monitoring solution for microprocessors and other digital systems.
• Offers a low power consumption design, making it suitable for battery-powered applications.
• The reset output is active-low, ensuring compatibility with various microcontrollers and logic circuits.

Advantages and Disadvantages

Advantages: - Wide supply voltage range allows for versatile use in different applications. - Multiple reset threshold voltage and timeout period options provide flexibility. - Low power consumption extends battery life in portable devices. - Small form factor and tape and reel packaging facilitate easy integration into PCB designs.

Disadvantages: - Limited number of reset threshold voltage and timeout period options may not meet specific requirements. - Lack of adjustable hysteresis may limit its suitability for certain applications.

Working Principles

The TCM809JVLB713 operates by continuously monitoring the supply voltage. When the voltage drops below the programmed threshold, the IC asserts a reset signal on the RESET pin. This signal remains active-low until the supply voltage rises above the threshold and the reset timeout period elapses.

Detailed Application Field Plans

The TCM809JVLB713 is widely used in various applications where reliable voltage monitoring and system reset functionality are required. Some potential application fields include:

1. Microcontrollers and Digital Systems: Provides a robust reset solution to ensure proper initialization and operation of microprocessors, microcontrollers, and other digital systems.
2. Battery-Powered Devices: Enables efficient power management by monitoring the battery voltage and initiating a reset when it reaches critical levels.
3. Industrial Control Systems: Ensures the safe and reliable operation of industrial control systems by monitoring the power supply and initiating a reset if necessary.
4. Automotive Electronics: Protects automotive electronic systems from voltage fluctuations and ensures proper functioning during start-up and operation.
