The MAX6381XR25D2-T is an advanced ultra-low current, low-voltage supervisor from Maxim Integrated. The device is a cost effective way to ensure system reliability in applications where electromagnetic interferences (EMI) degrade performance. The supervisor is ideal for use with various microcontroller-based systems, especially those high-speed, power-enabling systems where the supervisor is required to be extremely low-power.

The MAX6381XR25D2-T is a Power Management IC (PMIC) - Supervisors and its primary application field is in automotive, industrial, and medical systems. It is designed to provide a stable, low-power supply voltage to microcontrollers or other logic circuits in a variety of systems, while also providing accuracy and reliability in the face of EMI. This device includes a programmable Power-On Reset output, a adjustable reset voltage and a low active-state dropout voltage, thus providing optimal protection for microcontroller-based systems.

The primary working principle of the MAX6381XR25D2-T is that it provides voltage vs. time monitoring and sets a reset output when a specified, user-defined reset threshold is exceeded. The devices feature a 2-input OR gate that can be used to OR the reset input (reset out) of multiple ICs together. The reset then is fed back to the device to keep the reset active until the voltage is back in range. This ensures reliable and accurate monitoring of the system power supply.

The MAX6381XR25D2-T also features an adjustable reset voltage which provides a wide range of versatility in application selection. The devices can provide monitoring for any supply voltage ranging from 4V to 35V, making it an ideal device for a variety of voltage monitoring applications. In addition, the low active state dropout voltage ensures minimal power consumption when applied to a system.

The MAX6381XR25D2-T also includes a wide temperature range operation and is suitable for operation over the full temperature range of -40°C to + 185°C. The device is also capable of operating in extreme temperatures, from -45°C to +85°C, making it suitable for industrial, automotive, and medical applications. There is no need for manual reset or monitoring of a system’s voltage during start-up, making it an ideal device for high-reliability applications.

In summary, the MAX6381XR25D2-T is a well rounded PMIC - Supervisors that can be used in a variety of applications due to its wide range of operating temperature and voltage capabilities. The device provides a versatile and reliable solution that provides assurance of voltage accuracy and stability. It also is low power, low current, and features an adjustable reset threshold, so it can be configured to fit almost any application.
