ADM8322WC26ARJZR is a Programmable Low-Voltage Supervisor. It provides a cost-effective way to monitor supply voltages to detect an undervoltage or overvoltage fault. It is an effective solution for managing the risks of system level overvoltage fault conditions, when these conditions are caused by power supply or brownout failures.

Application fields of ADM8322WC26ARJZR7 include portable electronics, automotive, lighting equipment, general-purpose devices, industrial systems and medical systems. It can be used for detecting undervoltage and overvoltage conditions such as dead battery, short battery life and current malfunctioning. It can also be used for monitoring circuit shorts, inrush current and overcurrent protection. It is also used for board-level power monitoring, such as enabling voltage level monitoring of 5-12V systems, or 3-9V systems.

The working principle of ADM8322WC26ARJZR7 is based on a precision voltage threshold comparator that compares a regulated reference voltage to an external voltage. When the external voltage is below the programmed threshold, the output of the comparator goes low, indicating an undervoltage condition. When the external voltage is above the programmed threshold, the output of the comparator goes high, indicating an overvoltage condition. The comparator has adjustable hysteresis and can also be used to detect high/low conditions.

In addition, the ADM8322WC26ARJZR7 features an SMBus/I2C interface for digital control of settings and for programming the threshold levels. The device also features two IO pins for use in digital circuits. It is capable of controlling multiple outputs and has an integrated temperature sensor for thermal protection.
