XC6122C538MR-G is a power management integrated circuit (PMIC) specifically designed to provide a supervisory function for a variety of applications. The XC6122C538MR-G offers solutions for voltage supervisory and power-on reset generation, as well as active reset signal and proper reset signal indication. It provides an efficient way to protect the system from overvoltage and undervoltage by monitoring the supply voltage. In addition, it also provides system reset for keeping the system in a known state.

The XC6122C538MR-G has a high accuracy and fast response time which allows it to detect even the slightest deviations from the nominal voltage. It is capable of controlling a large current and providing a reset signal at the same time. It features a wide range of operating supply voltage (1.5V - 19V) and presents a low quiescent current. It is available in a 4-pin SOT23 package.

The XC6122C538MR-G is versatile and suitable for a range of applications. It is typically used in electronic modules such as processor/controller modules and will generate an early warning when the supply voltage drops or exceeds the preset level. It is also suitable for use in data entry and communications systems such as barcode scanners and GSM communications, where the reset signal prevents data corruption. XC6122C538MR-G can also be used in power management systems, where it ensures that the system remains in a stable and safe operating environment in the event of an over-voltage or undervoltage condition.

The XC6122C538MR-G working principle is based on the comparison between an internal reference voltage (Vref) and an external input (VIN). The dedicated output pin is then triggered based on the result of this data comparison. If the input voltage exceeds the Vref (overvoltage) or falls below the Vref (undervoltage), the output pin is then activated. When the input voltage returns to a good level, the output pin is deactivated.

The XC6122C538MR-G is also equipped with an active reset signal output which can be used to reset a system when the input voltage crosses predetermined upper and lower threshold. The active reset indicator pin serves to provide visual feedback that the XC6122C538MR-G is outputting a reset signal. This active reset indicator feature is designed in such way that the reset signal is asserted once the voltage deviates from the reference voltage, and then deasserted when the voltage returns to the normal operating range. Additionally, the reset signal output is able to hold an active state due to the built-in reset time-out period.

The XC6122C538MR-G is a useful and convenient solution for providing supervisor functions. It has a wide operating voltage range and is capable of controlling a large current while accurately providing a reset signal. Its ability to detect even the slightest deviation from the nominal voltage gives it an edge over other PMICs, and its active reset signal provides a reliable and efficient solution for voltage monitoring.
