Introduction

PMIC (Power Management IC) is an integrated circuit that can provide multiple power supply voltages and currents for the operation of various electronic devices. The use of PMICs can replace the traditional discrete components, thus reducing costs and increasing the reliability of electronic devices. The XC6122F722ER-G is a voltage supervisor with on-chip watchdog timer produced by NXP Semiconductors. It provides the essential safety protection to disconnect the circuit from the power sources to avoid overvoltage and undervoltage occurrences by monitoring the power supply voltage through its internal open drain comparator.

Application Field

XC6122F722ER-G is a voltage supervisor predominantly used in battery powered and standalone applications such as industrial control, automotive, remote systems and telecommunication services. It is well-suited for low supply voltage, low-power and miniaturized circuit designs without sacrificing system performance.XC6122F722ER-G is also an ideal choice for protecting the system against unexpected power-down events, detecting lower threshold events, and resetting the microcontroller during power surges or power-on reset conditions. The voltage supervisor performs an independent monitoring of the external input voltage feeds and system circuits, transmitting an active-low output signal whenever an unsafe voltage level is detected. It also features a shortcircuit protection circuit to protect the device from damage due to sudden spikes in power supply.

Features

XC6122F722ER-G is designed with several key features that make it a reliable and effective voltage supervisor. It has a low supply voltage range of 0.8V to 4.5V and a threshold voltage of 1.6V-2.5V. It is also capable of providing a 0.8V reset time with a reset active time of 150ms minimum, a watchdog time of 50ms minimum, and a watchdog reset time of 600ns minimum. The supervisor has an operating temperature rating of -40°C to 125°C and a standby current of 0.5uA minimum, ensuring low power consumption. It also provides a high level of flexibility for users with its various sleep modes, including wait, idle, and deep sleep. Users can also trigger or reset the device in real-time with its manual reset or external signal inputs.

Working Principle

XC6122F722ER-G is operated by continuously monitoring the system voltage, with the voltage monitored by the open drain comparator. When the system voltage is between the specified thresholds, the device remains in normal operation. When the system voltage drops below or rises above the threshold, the voltage supervisor triggers a reset or watch-dog timer. The reset output will then activate a signal to disconnect the circuit from the power sources, preventing further damage. The device will remain in this watchdog timer reset mode until the voltage reaches a safe threshold and the reset signal is deactivated.

Conclusion

XC6122F722ER-G is a highly reliable voltage supervisor designed for battery-powered and standalone applications. Its operating voltage range of 0.8V to 4.5V and its advanced features, such as manual reset and sleep modes, make it an ideal choice for protecting the system from sudden voltage fluctuations or power-down events. With its on-chip watchdog timer and internal open drain comparator, it ensures high reliability and system protection in these applications.
