XC61FN2212MR-G is a power management IC (PMIC) supervisor with integrated voltage monitor (IVM), which can detect overvoltage conditions and initiate reset or interrupt signals. It is designed to provide a complete reset and voltage monitor functions for system level protection and provides an active low reset signal to monitor the main power rail and system power on reset. The XC61FN2212MR-G can be used as a key component in safety circuits for medical, industrial and automotive applications to protect against overvoltages and overcurrent.

Working principle of XC61FN2212MR-G PMIC supervisor:

The XC61FN2212MR-G is based on an integrated dual rail voltage monitor, which can detect overvoltage conditions on two monitored power rail voltage levels. The PMIC supervisor monitors input voltage from 6 to 20V and provides a logic output output when an overvoltage is detected. The device can be configured to either trigger a reset or interrupt for operation, with a response time of about 5 ms. This internal voltage monitor has adjustable thresholds to prevent the device from providing a false reset or interrupt during major level changes of input voltages.

In addition to its overvoltage protection, the XC61FN2212MR-G also features an active low reset signal output as well as an active low output indicating power on reset. The monitoring time combines both short duration pulse on reset input and periodic monitoring of supply voltage, which is adjustable with external components. The optional power-on reset output is connected to a delayed active low reset output, which is triggered when the input voltage falls below a certain threshold.

The XC61FN2212MR-G also features an internal temperature monitor with an adjustable threshold, which offloads the system temperature monitoring burden. This enables it to be used in battery-powered systems to provide an early warning of an over temperature event. The device also has an adjustable power-up threshold and maximum input voltage, so it can provide system level protection for applications with a wide range of voltage levels.

Application field of XC61FN2212MR-G PMIC supervisor:

The XC61FN2212MR-G is a general purpose PMIC supervisor with broad application. The device offers protection from overvoltage, temperature protection, as well as power on/off and reset functions. It is widely used in consumer products and medical, industrial, automotive and other safety circuits for overvoltage and overcurrent protection. Its wide range of features, such as adjustable power-up, reset, and temperature thresholds, side-by-side monitoring of two power levels, and low quiescent current makes it suitable for battery-powered devices. In addition, its small package size reduces board space and improves mounting efficiency.

The XC61FN2212MR-G is a versatile PMIC supervisor that can provide system level protection and improved reliability for a wide range of applications. With its integrated voltage monitor, temperature monitor, and extensive adjustable threshold settings, it is an ideal solution for system level protection.
