The XC6119C42ANR-G is a PMIC—Supervisors from the ROHM Semiconductor brand. This device acts as a power control IC and has been designed to ensure that MCUs and microcontrollers are reliable and perform as expected for commercial and industrial applications. In this article, we will look at the application field of the XC6119C42ANR-G and explain its working principle.The XC6119C42ANR-G is a voltage monitor and supervisor circuit designed to detect faults in linear and switching power supplies. It features a built-in I²C-bus interface, allowing users to set different thresholds, circuit options, and power supply configurations. This device is ideal for a variety of settings, such as protection circuits that monitor power supplies; system sub-level monitors and reset circuits; and interface components, such as data and address buffers.The XC6119C42ANR-G has a wide operating voltage range of 1.2V to 3.7V, which makes this device suitable for use in a wide range of applications. It also features an I²C-bus interface that has a transfer rate range of up to 1MHz and a maxim speed of 10MHz. The device is capable of working in both 3V3 and 5V logic environments and has a wide variety of functions including fault protection, over-voltage protection, under-voltage protection, and abnormality detection.The XC6119C42ANR-G works by monitoring the input voltage and comparing it with the preset values. If the voltage falls below the lower threshold, the supervisor will trigger a reset. When the input voltage reaches the higher threshold, the supervisor will open the reset path and the power supply will turn on. The device also features a system monitor and reset logic to detect any system abnormality and reset the system if a fault is detected.The XC6119C42ANR-G has several advantages. It is a compact, cost-effective solution for any application that requires reliable power supply and fault detection. Its I²C-bus interface allows users to select and configure the device\'s functions easily and its wide range of thresholds and circuit options makes it suitable for many applications.In conclusion, the XC6119C42ANR-G is an advanced and versatile PMIC—supervisors, suitable for a wide variety of settings. Its adjustable thresholds and system reset logic make it a reliable choice for any application that requires fault and over-voltage protection, in either 3V3 or 5V logic environments. With its I²C-bus interface, this device is easy to configure to suit specific needs, making it a cost-effective and reliable option.
