PMIC (power management integrated circuit) - Supervisors are used for voltage detection and protection applications in overvoltage, undervoltage, and over-current scenarios. The ADM708ARZ-REEL is a P-channel Supervisory, Voltage Detector and Comparator IC with a built-in MOSFET. It provides a fast, accurate input voltage threshold detection with open-drain output. This device is especially designed for power supplies, overvoltage fault protection, and digital logic monitoring applications.

The ADM708ARZ-REEL device is a voltage detector which is suitable for low voltage, low power operations. It has two main characteristics: a low threshold of operation (1.245 V) and a maximum power supply of 18.0 volts. It is designed so that the output state is always the same regardless of input voltage. This means that the voltage across the output will always be between ground and a maximum voltage which is set according to the features of the device.

The ADM708ARZ-REEL is composed of a voltage detector, a voltage comparator, and an open-drain, single N-channel MOSFET (NFET) output transistor. The detector monitors the input voltage and compares it to two different thresholds. When the input voltage exceeds either of these two limits, the comparator will issue a logic low signal which will cause the NFET to switch on and pass current through the output. This will pull the output to ground and will cause the protection circuit to be activated.

The ADM708ARZ-REEL also has other features such as an internal pull-up resistor, an active low Enable pin and a Disable pin with a pull-up. The Enable and Disable pins act as override pins and are used to control the status of the output. If either one of the pins is pulled low, the NFET will be switched off, no matter what input voltage is applied.

The ADM708ARZ-REEL is ideal for a wide range of applications like power supplies, USB protection, system reset, overvoltage and undervoltage protection, automotive applications, and system monitoring. It is used for voltage detection and protection against faults such as overvoltage, undervoltage, and overcurrent. It is particularly useful in applications that require reliable and fast voltage detection, such as the protection of sensitive integrated circuits and systems.

The ADM708ARZ-REEL device is available in several packages, including a 4-pad SOT-23 package and an 8-pin SOIC package that has a built-in NFET switch. It also has a very low operating current which ranges from 0.2 to 1.2 μA. It operates on a supply voltage range of 1.7 to 18.0 V, and over temperature range of -40 to +85 °C.

Overall, the ADM708ARZ-REEL is a very useful device for voltage detection and protection applications. It is designed for low voltage, low power operation, and provides fast and accurate voltage detection with an open-drain output. It is available in various packages and has a very low operating current across its range of operating temperatures. It is ideal for applications like power supplies, overvoltage and undervoltage protection, automotive applications, and system monitoring.
