MAX6315US48D2+T is a Programmable Microprocessor Reset IC originally designed by Maxim Integrated and mainly used for reset and power-on reset. The device is in a fourteen-lead Dual-in-Line (DIP) package, which allows it to provide superior performance and flexibility. It includes an on-chip precision voltage monitor with an adjustable trip point, an asynchronous push-pull reset output, two open-drain outputs for active low power-good and output push-pull status, and two open-drain power-fail outputs. The MAX6315US48D2+T also includes an integrated fault-logging circuit to record the last ten reset events and provide perspective on power system transitions.

The Applications of MAX6315US48D2+T are varied and expansive, but it is most commonly used in server systems, personal computer motherboards, hard drives, battery-backed systems, and automotive applications. This IC is also applied to ensure that the voltage level of a system is always within a certain safe level. It is designed to provide a switch if the power supply level drops below the specified point. It can also help to prevent system crashes due to power failures by automatically shutting down the system before the critical levels are reached. All the features make it ideal for applications in general industrial and consumer embedded systems.

The Working Principle of MAX6315US48D2+T mainly revolves around the integrated voltage monitor. This monitor contains a precision voltage comparator and an internal reference voltage that are used to compare the system’s supply voltage with the monitor’s trip point. If the system voltage drops below the monitor’s trip point then the monitor will activate the reset output and initiate the reset sequence. When the power-good line is low, the reset output is enabled and the MAX6315US48D2+T IC will reset the system. The device also features an active low power-on reset (POR) output that monitors the supply voltage rail. When the supply voltage rises to the threshold, the POR output is triggered, enabling the system to be powered up.

Lastly, the MAX6315US48D2+T includes an integrated fault-logging circuit. This feature allows the device to track and record the last ten events that triggered the reset. The fault event log stores the timestamp, the type of reset event, the reset source, and other related information regarding the reset. The MAX6315US48D2+T can thus provide a wealth of information with regards to power system transitions or firmware/software hangs.

In conclusion, the MAX6315US48D2+T is an ideal choice for applications in the field of PMIC - Supervisors. It combines an on-chip precision voltage monitor with adjustable trip point, an asynchronous push-pull reset output, and two open-drain outputs for active low power-good and output push-pull status. The device also includes an integrated fault-logging circuit to record the last ten reset events and provide perspective on power system transitions. With its wide range of features, MAX6315US48D2+T is the ideal choice for a wide variety of applications.
