Introduction

The XC6108C39BGR-G is a voltage supervisor integrated circuit (IC) manufactured by Renesas Electronics. It is a power management IC (PMIC) suited for reset and monitoring applications in compact electronic devices. The device is a very compact solution that includes a Supervisor IC with a package measuring just 2.6 x 2.6mm and a range of features. It is suitable for ultra-low power applications.

Application Field

The XC6108C39BGR-G is well suited for applications that require a reset or voltage monitoring circuit. These include portable electronics such as cell phones, digital cameras, portable media players, and other consumer electronics where space and operating power are at a premium. The device can be used in automotive applications, industrial equipment, and many other types of embedded systems. The device can also be used in battery-powered systems, where the resets and monitors can provide the necessary protection against system overloads and failure.

Features

The XC6108C39BGR-G offers several features that make it an ideal PMIC for reset and voltage monitor applications. It includes an adjustable reset threshold that can be set for a specific range of system voltages. This feature allows users to ensure the device responds to voltage conditions within a specific range and minimizing power consumption. The device can detect slow falling, as well as rapid rising, voltage levels and produces a reset signal accordingly. It features an open-drain RESET output with an active high voltage, which allows the XC6108C39BGR-G to be interfaced directly to processors and other logic circuits.The XC6108C39BGR-G also features an adjustable timeout period. The timeout period allows the system to go into a reset condition after the voltage falls below its set voltage threshold for a specific length of time. This feature ensures that a wide range of system conditions can be detected. For example, fault conditions can be identified by a long period in which the voltage level remains below the set threshold.The device also includes a watchdog timer. The watchdog timer can be used to restart the system after a critical system error has been detected. This feature can prevent a system from entering a malfunctioning state, which can improve system reliability. Additionally, the XC6108C39BGR-G includes an output that starts measuring the time from the moment the reset signal is generated. This can be used to accurately measure the duration of the reset signal.

Working Principle

The XC6108C39BGR-G works by monitoring the voltage level of a system and issuing a reset signal when the voltage exceeds or drops beneath a specified threshold. The device uses an open-drain output, which means the RESET signal is asserted by pulling the open-drain output low. When the voltage level rises back above the threshold, the RESET signal is deasserted by bringing the open-drain output high.The device also features an adjustable timeout period feature. This feature allows the RESET signal to be issued after a certain time period has elapsed from the time the voltage entered a fault condition. This feature prevents a system from entering a malfunctioning state by forcing a reset after the fault conditioned and restarting the system.In addition, the watchdog timer feature is used to automatically restart the system after a certain amount of time has elapsed. This feature can be used to recover from system faults that cannot be reversed and ensure the system remains stable.

Conclusion

The XC6108C39BGR-G can be used for reset and voltage monitoring in applications where space is limited and very low power consumption is required. Its wide range of features make it suitable for a variety of applications, including consumer electronic devices, industrial equipment, automotive applications, and more. Its adjustable reset threshold, timeout period, and watchdog timer features are all useful for ensuring system stability and reliability.
