X4045M8I-2.7A is a supervisor device from the Power Management Integrated Circuit (PMIC) family. This chip integrates the reset, watch-dog, over-temperature protection, and power sequencing functions. For RTC battery-backup and supply, it also has LDO linear regulator output. The purpose of a supervisor-type chip is to protect the system components from being destroyed when unexpected malfunctions happen inside the system.

The X4045M8I-2.7A is widely used in many system applications, including servers, workstations, personal computers, computer motherboards and set-top boxes, etc. It also offers great design flexibility and multi-functionality. It has 8 pre-programmable due points to detect system status and reset cpu. The over-temperature protection (OTP) circuit is useful to prevent thermal-induced mayhem.

The working principle of the X4045M8I-2.7A is based on the following steps. First, the supervisor provides a reset signal to the system upon power-on when the voltage of the power input exceeds the pre-set value. In addition, it monitors the voltage and current for each of the system components, triggering rest when any one of them is out of the normal levels. The OTP monitors the temperature levels of the system and shuts down the system should a temperature out of range is detected. Finally, it will generate the reset signal and restart the system when the system is powered on and the conditions are met.

The X4045M8I-2.7A also offers sequence control between the system component power-on and power-off. It enables the system\'s power-up and power-down sequence, in order to avoid any component of the system failing due to the inrush and current surge when it is being turned on or off. The sequence control is programmed by user’s configuration within certain steps, delay or timing requirements.

In addition, the X4045M8I-2.7A can also be used as a battery-operator device. It has a linear regulator LDO output, which allows the system to be operated from a battery without any additional components. As a result, it not only eliminates external components, but also offers great convenience to the system designer.

As a PMIC supervisor, the X4045M8I-2.7A chip is a valuable component for system operation. It is designed to offer various functions, such as resetting, sequencing, monitoring and protecting the system components. All these functions help protect the system from being damaged due to its internal malfunctions, so as to ensure a longer system life. It also enables sequence control between the system component power-on and power-off, in order to reduce the risk caused by current surge when the system is turned on or off. Finally, it allows the system to be run on battery backup, thus providing great convenience to the system designers.
