The X5045V14I is optimized for use with microcontrollers, microprocessors and digital signal processors. It is designed for applications that require high levels of reliability and precision, such as in automotive and medical device applications. The device is also suitable for applications where power efficiency is paramount.

Features

The X5045V14I offers a number of advanced features, including:

• High-efficiency, low-noise linear regulators, allowing for precise power management
• A built-in, programmable, adjustable-delay reset pulse
• Programmable watchdog timer
• Automatic & manual reset generation
• Open drain output, suitable for a variety of power architectures
• Overvoltage, undervoltage, and overcurrent protections
• And more!

Working Principle

The X5045V14I is designed to protect the system from abnormal conditions such as overvoltage, undervoltage, and overcurrent events. When normal operation is disrupted and an abnormal condition is detected, the X5045V14I will generate a reset pulse and activate the watchdog timer. The reset pulse will reset the system and the watchdog timer will delay the activation of the reset pulse, allowing the system to continue operating normally.

The X5045V14I also provides a programmable adjustable-delay reset pulse. This allows the user to adjust the timing of the reset pulse if needed. This is particularly useful in applications where precise timing is required. Additionally, the device offers open drain output, allowing for a variety of power architectures.

Conclusion

In conclusion, the X5045V14I PMIC supervisor is an effective solution for a variety of applications, providing reliable monitoring and protection from overvoltage, undervoltage, and overcurrent conditions. The device offers advanced features including high-efficiency linear regulators, built-in programmable adjustable-delay reset pulse, programmable watchdog timer, automatic and manual reset generation, and open drain output. This makes the X5045V14I an ideal choice for applications that require precision, reliability, and power efficiency.
