PMIC - Supervisors are an important type of integrated circuit, which are used to handle power management functions and ensure the secure operation of electronic circuits. The XC61HN1812MR-G is an example of such an integrated circuit, and it is designed to monitor power supply rail voltages, detect faults, and drive reset and interrupt events. This article will explain the application field and working principle of the XC61HN1812MR-G.

The XC61HN1812MR-G is a supervisor IC, which is used to ensure the safe and reliable operation of electronic circuits. It monitors power supply rail voltages and can detect inrush current, overvoltage, undervoltage, and overcurrent conditions. The XC61HN1812MR-G has a wide input voltage range of 2.5V to 18V, and it is able to drive reset and interrupt events when a fault is detected.

The XC61HN1812MR-G is used in applications such as communications, consumer, industrial, and automotive systems. In communications systems, it can be used to monitor system power rails and detect power supply glitches, overvoltage, and overcurrent conditions. In consumer and industrial applications, it can monitor the power supply for signs of overvoltage, undervoltage, or inrush current. In automotive systems, it can be used to detect the presence of the ignition line and to monitor the power supply on the vehicle for signs of overvoltage or undervoltage.

The XC61HN1812MR-G is capable of providing parallel logic outputs for reset and interrupt events. It has an active low reset output that drives an associated logic device to reset the system when a fault is detected. An active low interrupt output is also provided, which can be used to activate an interrupt handling routine in the associated system. The reset and interrupt outputs are open drain, which means they are able to sink current to ground, but they cannot source current.

The XC61HN1812MR-G is also capable of providing adjustable timing. It can be configured to delay reset and interrupt events in order to allow the system time to respond and recover. The reset and interrupt outputs have a maximum current sinking capability of 24mA, which allows them to drive external logic devices.

The XC61HN1812MR-G operates on a wide temperature range from -40ºC to +125ºC and is available in surface mount and through-hole packages. The IC has a high operating temperature range, which makes it suitable for use in demanding automotive, industrial, and communications applications.

In conclusion, the XC61HN1812MR-G is a supervisor IC, which is used to monitoring power supply rails and drive reset and interrupt events when faults are detected. It is used in industrial, automotive, and communications applications and is capable of driving reset and interrupt events with adjustable timing. The IC has a wide temperature range and is available in surface mount and through-hole packages.
