X40034V14I-B

The X40034V14I-B is a comprehensive system supervisor device that combines a three-channel watchdog timer, two power-on reset (POR) circuits, an LVI detector, a temperature monitor, and a supervisor-initiated power-down circuit. It is designed to prevent system malfunction and damage due to microprocessor (uP) and external system faults. The device is optimized for use with the latest microprocessors that can reduce system power consumption.

Application Field

The X40034V14I-B is suitable for use in a variety of computer and industrial systems, including portable computers and notebook computers, printers, stoves, air conditioners, washing machines and refrigerators, as well as industrial components that rely on microprocessors for system control.

In addition, the X40034V14I-B is typically used in applications where power consumption is a concern. It is well suited for applications requiring low power consumption, such as battery-operated systems, since it combines several components (PORs, LVI detectors, temperature monitors, and watchdog timers) into one device.

Working Principle

The X40034V14I-B provides a range of protection features to guarantee system integrity and reliability. These features include:

• Three independent watchdog timer circuits - The three watchdog timer circuits are capable of monitoring the program sequencing of each system processor, preventing system malfunctions due to uP software or system faults.
• Two power-on reset (POR) circuits - The two POR circuits provide an effective way of monitoring system start-up and ensuring that the system is reset or restarted if an abnormality is detected.
• LVI detector - This component is used to detect any abnormality in the system’s internal Low Voltage Interrupt (LVI) signal and provide a reset or restart signal to the system.
• Temperature monitor - The temperature monitor is used to detect any abnormality in the system’s internal temperature signal, preventing system damage due to overheating.
• Supervisor-initiated power-down circuit - The supervisor-initiated power-down circuit is used to shut down the power supply to the system in the event of an abnormality.

In addition, the X40034V14I-B is equipped with a wide range of features that make it highly versatile, such as an adjustable watchdog timer timeout and an adjustable voltage threshold level for the LVI detector and temperature monitor.

The X40034V14I-B is an ideal solution for applications that require reliable system protection and low power consumption. It is designed to provide superior system integrity and reliable system operation for new and existing designs.
