XC6122A450ER-G

PMIC - Supervisors

The XC6122A450ER-G stands for Poly Microsystems, Safety Supervisor. It is a type of safety supervisor, a very important component in a wide array of electronic systems. It is used to monitor the line voltage and prevent over voltage or short circuit, and effectively protect the system.

An XC6122A450ER-G typically consists of an 8-pin package, including an internal under-voltage input, and a robust voltage detector. It features a high precision voltage detector to detect momentary fluctuations, and offers a low power operation of 0.6mA, while the maximum ultra low-voltage detection range is 5.6V. It also has a high current capability, up to 400mA.

Applications of XC6122A450ER-G

The XC6122A450ER-G can be used in various applications such as LCD displays, AC-DC and DC-DC converters, line oil boilers, hospital medical equipment and consumer electronic products. It is particularly suitable for line over/undervoltage protection in various power systems, allowing for reliable operation under high voltage and lower power consumption.

Working Principle of XC6122A450ER-G

The XC6122A450ER-G implements a two-stage monitoring principle. The first stage is the Under-Voltage Comparator, which can detect if the line voltage is too low and will immediately activate the protection. The second stage is the Over-Voltage Limit Protection, which will trigger if the line voltage exceeds the specified limit. This two-stage monitoring principle effectively protects the system from over-voltage and under-voltage conditions.

The XC6122A450ER-G has a high precision voltage detector, which can accurately detect momentary fluctuations and respond accordingly. Upon detecting a prestored voltage, it will trigger the over voltage protection and shut down the system. It can also detect dropout events, allowing for accurate and reliable protection against damaging over-voltage.

The XC6122A450ER-G also has low power consumption, allowing for efficient operation with battery powered devices. In addition, it supports a wide operating temperature range and provides a high level of protection.

Conclusion

The XC6122A450ER-G is a polymicrosystems safety supervisor and is used in many different applications. It features a high precision voltage detector and low power consumption, and can detect momentary voltage fluctuations and provide protection against over-voltage and under-voltage conditions. It is an essential component in power systems providing reliable operation under high voltage and low power consumption.
