Introduction

X4283S8I-4.5A is a PMIC - Supervisors device that combines the functions of different supervisors in one package. It has a four-channel redundancy monitor, an overvoltage supervisor, a power-on supervisor, a wake-up controller and safety timers, making it an ideal solution for device supervision in industrial, control, and automotive applications. This device helps to improve system safety and reliability by providing voltage monitoring and reset functions, allowing a device to quickly respond to power glitches and abnormal conditions. It also helps to reduce overall system costs by integrating multiple supervisors into a single device.

Features

The X4283S8I-4.5A offers the following features: - Four-Channel Redundancy Monitor - This feature provides an accurate voltage monitoring across up to four independent input channels. This helps to ensure that voltage mismatches and no power up safety errors are detected. - Overvoltage Supervisor - This feature provides an automated overvoltage protection function for each input channel. It will set an overvoltage flag when the input voltage exceeds the device’s preset upper and lower thresholds. - Power-on Supervisor - This feature provides a power-on reset signal that can be used to reset the target system in response to a power glitch or other abnormal conditions. - Wake-up Controller - This feature will allow the X4283S8I-4.5A to be used as a wake-up controller, enabling it to respond to a low-power or sleep mode by generating a wake-up signal to the target system. - Safety Timers - This feature monitors the elapsed time of a system reset cycle, and will generate an alert if the reset cycle takes too long. This helps to ensure that all systems are reset within a predetermined time period.

Applications

The X4283S8I-4.5A is a versatile device that is well-suited for a wide range of industrial, control, and automotive applications, including: - Factory automation- Machine control- Automotive systems - Power management- Surveillance systems - White goods- Telecommunications- Networking

Working Principle

The X4283S8I-4.5A is a multichannel supervisor device that monitors the voltage of up to four independent input channels. Each channel is monitored independently, and the device will set an overvoltage flag when the input voltage exceeds the device’s preset upper and lower thresholds.The device also provides a power-on reset signal that can be used to reset the power system in response to a power glitch or other abnormal conditions. When the power reset signal is issued, the device will initiate a pre-configured reset cycle, which can be monitored through the device’s safety timers. Once the reset cycle is finished, the device will generate a reset signal, which can then be used to reset the target system.In addition, the X4283S8I-4.5A can also be used as a wake-up controller, allowing it to respond to a low-power or sleep mode by generating a wake-up signal to the target system.

Conclusion

The X4283S8I-4.5A PMIC - Supervisors device combines the functions of different supervisors in one package, making it an ideal decision for a variety of industrial, control, and automotive applications. It provides a four-channel redundancy monitor, an overvoltage supervisor, a power-on supervisor, a wake-up controller and safety timers, helping to improve system safety and reliability by providing voltage monitoring, reset functions, and power-on reset signals.
