PMIC - Supervisors are circuit components for providing protection for a device in case of power related issues, such as too high power, overvoltage, or an excessive current. Generally, they supervise the power pins of ICs in a board to protect the IC as well as the board itself. A particular example of a PMIC - Supervisor - the MXD1816XR29+T - has many applications in various fields, as it can be found useful when it comes to protecting the device against any kind of overvoltage, or added stress resulting from a power surge or fault on the power line. A few samples of its application field may include Automotive Control Modules, Industrial Controllers and Processors, and other devices with a wide power line range.

The MXD1816XR29+T is a highly integrated Digital Supervisory Circuit with programmable function and number of pins. It works by monitoring multiple input pin voltages, current, and temperature. With the help of its “Peak-and-Hold” input pin configuration, it can detect any level of above-normal voltage or current as well as any other variations arising from a power supply fault. Moreover, it uses an on-chip temperature sensor to monitor the temperature level of the device. All in all, can work well even in the conditions with high voltage transients, offering certain amount of protection for the device.

The functioning mechanism of the MXD1816XR29+T is very straightforward. It is a two-terminal device with a voltage and a ground pin. This two-terminal device connects to the two pins of the device, which should be supervised. The control circuitry of the MXD1816XR29+T periodically monitors the voltage and current on these two pins in order to detect any abnormalities. In case of any abnormality, it automatically takes the necessary preventive measures to protect the device from being damaged.

In the case of temperature supervision, the built-in temperature sensor integrated into the MXD18
