Power management ICs, more commonly referred to as PMICs, are highly integrated chips designed to support the monitoring and control of power systems in a variety of electronic devices and systems. PMICs are designed to convert and manage energy from multiples of sources – such as batteries, DC/AC adapters, and power supplies – to power up and maintain a variety of electronic systems.

In this article, we take a look at the XC61GN3002HR-G, a PMIC unit from Renesas Electronics. This device is part of a larger series of Supervisors, which have been developed to manage and supervise power systems more accurately and efficiently in different kinds of applications.

XC61GN3002HR-G: Overview and Key Features

The XC61GN3002HR-G is a low power and low noise supervisor IC. It is designed to provide highly reliable supply voltage monitoring and voltage supervisory functions during power-up, power-down, and normal operation of electronic systems.

This PMIC is built to be multi-voltage compatible, meaning it can be used in applications with a maximum input voltage of 20V. It is also capable of monitoring and providing optimal voltage output for a wide range of voltages from 0.9V to 17V.

The XC61GN3002HR-G also offers low power consumption, as it is designed to operate with a total supply current of 8.5µA. This saves energy and also aids in extending battery life.

In addition, it features various protection features such as under voltage, over voltage, and thermal protection capabilities. This helps maintain smooth and continuous power supply while also protecting the IC itself from any potential damage due to external voltage variations.

The XC61GN3002HR-G is available in a 5-pin MSI SOP package and is capable of operating within a temperature range of -40°C to +85°C.

XC61GN3002HR-G Application Fields and Working Principle

The XC61GN3002HR-G is a highly reliable voltage supervisor IC and can be used in a wide range of commercial, automotive, and industrial applications. Some of the common application fields include consumer devices such as mobile phones, tablet PCs and digital cameras, embedded devices such as electrical household appliances and automotive parts such as engine immobilizers and entertainment systems.

As far as its working principle is concerned, the XC61GN3002HR-G utilizes an internal voltage reference source and an error amplifier. The on-chip voltage reference source is powered by an external source and is used to compare the voltage of the external power source with the nominal voltage.

If the external voltage is below a specified threshold, the error amplifier triggers a power-on reset, which then causes the output reset signal to assert. This reset signal can then be used to initialize the system and then, if desired, cause all of the system’s power rails to turn on.

If the external voltage is above the set threshold, the error amplifier does not assert the power-on reset and the system is allowed to continue normal operation. In addition, the XC61GN3002HR-G provides an adjustable overvoltage monitoring threshold and an adjustable undervoltage monitoring threshold.

The XC61GN3002HR-G also offers reverse battery protection, which means that it can still detect and monitor the system’s power when the battery is connected in reverse. This ensures the system does not receive a damaging amount of power.

In summary, the XC61GN3002HR-G is a low power, low noise supervisor IC, designed to provide highly reliable supply voltage monitoring and voltage supervisory functions for a range of commercial, automotive and industrial applications.
