The MAX6366PKA23+T is an extremely high-performance power management supervisory device that enables a wide range of power management applications. The device is typically utilized as a polyphase supervisor for multiple voltage rails. The power supervisory and monitoring features include a 265 ms reset timeout, active-low reset with manual reset override, a monitor input for monitoring the voltage source, and an adjustable reset timeout.

The MAX6366PKA23+T has a monitoring range of 3.2 V to 8.2 V and can monitor 2 V, 3.3 V, and 5 V supplies. The device offers an adjustable reset timeout from 150 μs to a maximum of 265 ms. It is also capable of generating an on-board reset signal to many different types of microcontrollers and can be used as a stand-alone reset controller for power supplies with reset outputs.

The MAX6366PKA23+T has a wide range of application fields, including computers, embedded systems, handheld applications, and network equipment. The device can be used to create innovative power supply designs, facilitate fast power switching and evaluation, provide high reliability power management, reduce board space, and provide fault coverage.

The MAX6366PKA23+T\'s working principle is based on the simple idea of recognizing when a power supply voltage has dropped below a certain threshold. This is accomplished via two comparators which feature a hysteresis voltage of 2.5 mV. A comparator is connected to the power supply rails of 3.2 V and 8.2 V, while the other is connected to an internal reference voltage of 3.2 V in order to monitor voltage drops.

When the monitored voltage drops below the reference voltage, the comparator output goes low, initiating the reset process. The reset time can be adjusted with the input pin for a reset timeout period from 150 μs to 265 ms. If the input voltage is at or above the internal reference voltage after the timeout period, the reset output pin deactivates and the device returns to its regular operating mode.

The MAX6366PKA23+T is capable of providing powerful active voltage monitoring features, allowing for easy and fast restarts in the event of a power supply fault. Its wide range of application fields make it the ideal choice for many power management applications. The device\'s adjustable reset timeout and advanced reset controller make it suitable for a variety of microcontroller applications, as well as embedded systems and handheld products.
