MAX6461XR25+T is an application field and working principle of PMIC (Power Management Interface Circuit). It is designed to help with the development of ultra-low power and high-performance embedded systems. This device can provide a low-noise, low-ripple output for voltage supervisory, system power supply sequencing, a precision monitoring and control of supply voltages, and an accurate system clock for synchronizing operations. It is also reliable, flexible and cost-effective, making it an ideal choice for embedded systems.

The MAX6461XR25+T provides a user-configurable analog voltage supervisory circuit with a fixed voltage threshold, enabling system monitoring of supply voltages compatible with traditional power management logic in a very small package. It can detect voltage levels with an accuracy of ±1.25% over a 0°C to 70°C temperature range, with an adjustable 0°C to +85°C margin. This makes it especially suitable for ultra-low power and highly sensitive embedded designs.

It can detect over- and under-voltage conditions and provide up to 2V/ms of fast rising time for faster system wakeup. The device also features an internal voltage reference that can generate accurate system output clocks of up to 1MHz (18MHz for the T version). In addition, it has an integrated hardware reset output that can be controlled by a microprocessor or other logic basis for system reset and debug.

The MAX6461XR25+T also provides precision system power supply sequencing capabilities that allow users to control multiple power supplies in an embedded system. It offers programmable delays and built-in fail-safe mechanisms to ensure that the power supplies are turned on/off in the desired order. This ensures smooth and reliable power supply sequencing, even if there are unforeseen system failures or power supply brownouts.

The MAX6461XR25+T features a high-speed serial interface, enabling quick and easy connection to a microprocessor or other controller. In addition, system power supply sequencing and monitoring can be implemented in a few lines of code, eliminating the need for complex external circuitry. Moreover, the device can be powered from VCC or a 3V to 5.5V input, making it suitable for both low- and high-voltage systems.

Overall, MAX6461XR25+T is an excellent application field and working principle of PMIC-Supervisors. Its integrated voltage reference and power supply sequencing capabilities make it an ideal choice for highly sensitive and ultra-low power embedded designs. Moreover, its small size and simple design make it easy to integrate into any embedded system. As a result, MAX6461XR25+T has become a popular choice for many embedded system designers.
