MAX16083AXR46B+T is a member of the MAX16083 family of Supervisors with Low-Voltage Detect, Sequencing, and System Reset. It is a highly integrated late-stage sequencer and integrated 1.2V reset supervisor from Maxim Integrated. This device is highly versatile and provides an extensive list of system-level functions including power-up sequencing, power-down sequencing, system reset generation, PVCC/PCORE regulation, and timed delays on power-up/power-down.

The MAX16083AXR46B+T can be used for a wide variety of applications, such as automotive, cellphones, servers, and notebook computers. It is ideal for use in systems that require high-precision power-up voltage sequencing, reset management, and system monitoring.

MAX16083AXR46B+T working principle is based on a low voltage detect (LVD) circuit. The LVD circuit works by sensing the voltage at the PVCC or PCORE input pin (VIN) and generates a logic signal indicating whether or not the voltage is within the specified range. The logic signal is then used to enable the system reset circuit. The reset active signal is then passed to the system, where it is used to reset the system when the voltage reaches the undervoltage threshold.

The reset active signal is programmed with the Reset Active Time, which is the time from the LVD detect to the system reset. This time can be preset in the MAX16083AXR46B+T to ensure the system reset signal is generated at the correct time for system stability.

The MAX16083AXR46B+T also includes a timer, which can be programmed to delay the system reset signal. This allows the system to detect a voltage drop, wait for a period of time, and then activate the reset signal if it does not recover. This can prevent false system reset when high frequency noise is present on the power rail.

In addition, the MAX16083AXR46B+T also provides a set of power-good inputs, which are used to detect the output of other power supplies in the system. The power-good input can detect when a power supply is not in regulation or not present in the system, and can be used to generate system reset when the power supply fails.

The MAX16083AXR46B+T is designed to provide the flexibility and reliability needed for mission-critical systems. It offers a variety of features such as integrated voltage protection, adjustable reset active time, delay, power-good inputs, and reset outputs for different configurations. It also includes a reset output latch, which allows for an extended reset condition if the voltage is lower than specified for an extended period of time. The MAX16083AXR46B+T is an ideal solution for ensuring reliable operation of critical systems.
