PMIC - Supervisors is a field of application that manages ICs that monitor electronic circuits and systems to prevent overvoltage, overcurrent, over-temperature and low battery conditions. The MAX6381LT30D2+T is a particular supervisor IC that provides circuit protection against overvoltages and/or overcurrents. It is primarily used for power system monitoring and protects logic circuits from overcurrent, overvoltage, and over temperature conditions.

The MAX6381LT30D2+T features an active-low reset signal. The reset signal is asserted when at least one of the voltage, current or temperature thresholds is exceeded and will remain active until all monitored thresholds have returned to normal. The IC can also be configured to provide an active-high reset signal, an active-low enable signal, or both.

The MAX6381LT30D2+T has an open-drain output that is capable of sinking up to 100 mA of current. This means that the IC can be used to control other ICs, and is suitable for applications that require higher current sourcing and sinking capabilities.

The other important feature of the MAX6381LT30D2+T is that it is able to monitor multiple voltages, currents, and temperatures simultaneously. The IC has two voltage inputs and one current input with adjustable voltage thresholds, current trip thresholds, and temperature trip thresholds. It also has a programmable delay of up to 1 second, meaning that the reset signal will not be activated immediately once the thresholds are exceeded, and will instead be activated after a certain delay.

The MAX6381LT30D2+T also features an Analog-to-Digital Converter (ADC) that can be used to continuously monitor the voltage and current of two of the inputs. The ADC input can be configured to operate in either the single-ended or differential mode, meaning that the IC can be used to monitor not only digital inputs but also analog inputs.

The MAX6381LT30D2+T works by comparing the incoming voltage or current inputs to the programmed thresholds. When the thresholds are exceeded, a reset signal is generated and sent to the system. The reset signal can either be an active-low or an active-high signal, depending on the configuration. If the temperature is exceeded, an assertion is sent to the thermal management circuit that can shut down the system.

In summary, the MAX6381LT30D2+T is an IC that provides circuit protection against overvoltages and/or overcurrents and can be used for power system monitoring. It features an active-low and/or active-high reset signal, an open-drain output capable of sinking up to 100 mA of current, two voltage inputs and one current input and adjustable voltage, current, and temperature thresholds. It also has a programmable delay of up to one second, and an ADC input that can be configured to operate in either single-ended or differential mode.
