Power management integrated circuits (PMICs) are a class of electronic components that are designed to provide power to a variety of electronic systems and devices. PMICs are typically used to provide better power efficiency, minimize power loss and minimize power consumption in the final product. Supervisors, one type of PMIC, are used to monitor for functions that require immediate response, such as resetting a system after a power failure. The XC6122E447MR-G Supervisor is an example of such a device.

Overview of XC6122E447MR-G Supervisor

The XC6122E447MR-G Supervisor is designed to provide integrated reset and reset protection to digital systems. It features a low-current standby mode, a wide input voltage range, and an adjustable reset output delay. The device is offered in a space-saving 8-pin plastic and metal SOIC package, making it ideal for applications that require a small form factor. Additionally, the device features a low-voltage brownout detector and an adjustable watchdog timer.

Application Fields

The XC6122E447MR-G Supervisor can be used in a range of applications, from communications and industrial to automotive, within industrial control systems. The device is most often used in automotive systems due to its low-voltage and low-current operating requirements. It can be used to provide protection for a range of onboard systems, such as automotive displays, ECU systems, power supply systems and other automotive processors.

Working Principle

The basic function of the XC6122E447MR-G Supervisor is to provide reset protection for a digital system in the case of power failure or voltage instability. The device works by monitoring the voltage of the system and then performing a reset if the voltage drops below a certain threshold. The size of the threshold voltage and the length of time before reset is determined by the settings of two voltage sense pins on the device.

Once the preset trigger threshold is reached, an internal reset signal is activated, and the system is reset. Once the voltage is restored, the supervisor will automatically terminate the reset sequence and the system will resume normal operation. The reset pin can also be manually triggered by an external signal if necessary.

The XC6122E447MR-G Supervisor also includes other features, such as a watchdog timer, a low-voltage detector, and an adjustable reset output delay. The watchdog timer is used to periodically monitor system activity and reset the system if no activity is detected. The low-voltage detector monitors the voltage level and triggers a reset signal if the voltage drops too low. The adjustable reset output delay can be used to set the minimum reset pulse width. By utilizing these features, the supervisor can protect a digital system from power failures or other power disturbances.

Conclusion

The XC6122E447MR-G Supervisor is a powerful and versatile PMIC suitable for a range of applications. It is capable of providing reset and reset protection for a digital system, as well as providing additional protection with the inclusion of a watchdog timer, a low-voltage detector, and adjustable reset output delay. The device is packaged in a small 8-pin plastic and metal SOIC package, which allows for easy integration into a wide range of systems.
