Power management integrated circuit (PMIC) is a kind of very important semiconductor device. They are used in the power management of mobile phones and other portable devices, and they have the ability to produce multiple voltages from a single source. Supervisors are one type of PMICs that perform the critical task of monitoring conditions and providing outputs to signal different events, such as undervoltage, overvoltage etc. In this article, we will discuss about one such type of supervisor, XC6122C416ER-G and its application field and working principle.

Features of XC6122C416ER-G

The XC6122C416ER-G is a power-management supervisor IC for monitoring the power supply voltage of systems. It is an ultra-low-voltage (ULV) supervisor IC with a very low power consumption of 1.5μA as well as a wide operating temperature range of -40 to 125°C. It offers a high level of accuracy with a ±1.0% reset threshold tolerance, while its robust detection circuit helps in noisy system environments.

The XC6122C416ER-G also offers a variety of reset functions, including manual reset and WDT reset, as well as an output function such as low-voltage detection (LVD) and CTR reset. The LVP function ensures reliable reset under low-voltage conditions, while the CTR reset function provides a longer reset timing for system lockout prevention. Additionally, the XC6122C416ER-G supports both active-low active-high reset outputs, making it suitable for a wide variety of applications.

Application Field

The XC6122C416ER-G is ideal for monitoring the power supply voltage of mobile devices, consumer electronic products, and industrial control systems. It can be used for a variety of purposes, such as power-supply system reset, reset of microprocessor-based systems, monitoring of power-supply voltage and temperature, as well as a watchdog timer function.

The XC6122C416ER-G is especially suitable for use in consumer electronics, such as digital cameras or cameras, portable audio players, PDAs, and other storage devices. Its ULV design and flexible functionality make the XC6122C416ER-G the ideal choice for such applications.

Working Principle

The XC6122C416ER-G operates using a simple voltage threshold detection circuit. It measures the voltage of the system and when the voltage drops below a certain threshold, the reset output of the device is activated. The device has four different reset thresholds, with the thresholds being set to ±1.0% of the Vcc voltage. The reset output signal is active when the input voltage is below the preset threshold, and goes back to inactive when the voltage returns to normal.

The XC6122C416ER-G has two reset output signals, active-low and active-low, which can be configured to control different actions in the system. The device also has an input voltage monitoring terminal that is used to detect system voltages, and an LVP (low-voltage detection) pin which monitors and reports a lower voltage than the reset thresholds.

In addition to reset output, the XC6122C416ER-G also has an output function called low-voltage detection (LVD). This function monitors the input voltage, and if the voltage falls below a certain threshold the dedicated LVD output pin is activated. The output level and reset timing of the LVD output is configurable, allowing the user to set the appropriate parameters for their application.

Finally, the XC6122C416ER-G also contains a watchdog timer function. This function can be used to detect system faults in the event of a system crash or hang. The watchdog timer can also be configured to timeout at various intervals and will generate an active low reset output if the specified time has been exceeded.

Conclusion

The XC6122C416ER-G is a PMIC - Supervisors IC that is ideal for power-supply monitoring in many different applications such as mobile devices, consumer electronics, and industrial controls. The device provides a variety of features, including reset output and low-voltage detection, as well as watchdog timer. The combination of these features and the ultra-low-voltage, wide temperature range make the XC6122C416ER-G an ideal choice for applications which require higher levels of accuracy and robustness.
