Power Management Integrated Circuit (PMIC) is an integrated circuit dedicated to power management applications. Specifically, PMICs help to monitor and control the voltage supplied to a chip or system. Globally, the demand for PMIC is increasing due mainly to the growth in a variety of electronic devices such as smartphones, tablets, and other electronic appliances. Among the different types of PMICs, Supervisors are chipset solutions that provide high accuracy to monitor noisy power and reset the system, warning against invalid input voltages.

XC6119N31ANR-G is an integrated voltage supervisor from X-Ceptor series of NXP Semiconductors. This device offers an ideal cascade protection designed for two-level reset/power-on reset circuit. With a combination of delay output and glitch-free reset output, it clears false reset signals, especially with high levels of transients. Its combination of over, under, and low voltage detection at both supply and for various internal node monitoring provides flexibility for reset thresholds.

XC6119N31ANR-G has an operating voltage range of 2.0V to 5.35V and typical operating current of 125μA. It houses a 16-pin TQFN (Thin Quad Flat Packaged No Lead) package with a built-in delay function. The device came with an adjustable delay, a watchdog and a power-on reset timer with a 1.1-second power-on reset delay and an adjustable reset timeout setting up to 16 seconds. Its integrated detector output provides buffer protection for system reset control. Its default open-drain reset signal is 33kHz frequency with a valid reset input voltage range of 3.0V to 4.6V. This device’s reset output is also protected against inputs higher than the specified voltage.

XC6119N31ANR-G’s working principle is relatively simple. It houses an integrated circuit known as a voltage detector. This detector monitors the voltage of a certain node and triggers the reset output pin when it senses that the voltage has dropped or is too high. The on-board delay timer controls the reset signal output valid time. This timer can be adjusted to provide a delay from 0 to 16 seconds, depending on the requirement. XC6119N31ANR-G features an integrated Schmitt-trigger input, which eliminates the need for external components. It also has an adjustable timeout feature that prevents stuck resets that can occur when the voltage being monitored is low for an extended period.

XC6119N31ANR-G is suitable for various applications such as printed circuit boards (PCB)s and embedded systems. It is especially suitable for the automotive industry where redundant system reset is required according to the ASIL (Automotive Safety Integrity Level) procedure. Moreover, it is also applicable in computers, handheld devices, medical equipment, digital home appliances and power supplies.

In conclusion, XC6119N31ANR-G is a powerful integrated voltage supervisor with different features that can be adjusted to provide better protection against invalid input voltages. Its properties make it a suitable solution for several industrial applications, especially those with stringent safety requirements. This device presents users with an easier and more efficient way to manage their PCBs and embedded systems.
