Power Management Interface Controllers (PMIC) are electronic components that are used to supervise and control power supplies across multiple voltage domains and subsystems. They play an important role in power management and optimization in a range of fields, including consumer, industrial, automotive and health care applications. A type of PMIC known as a supervisor is specifically designed to detect power-system faults and safely reset a system in a fault condition. The MAX6314US26D4+T is a Bi-Supply Supervisor with two voltage-sensing inputs and one active-low output signal.

The MAX6314US26D4+T is a low power, reset supervisors featuring an active-low, open drain reset and reset-enable output with an operating voltage range from 2.5V to 5.5V. Its open drain output operates with an input voltage range from 1.2V to 5.5V for maximizing flexibility for a wide range of applications. The IC features a voltage-monitored window comparator that is used to detect when the supply voltages fall below factory-trimmed thresholds. Additionally, the IC contains an internal timer which provides a minimum reset pulse width of 68msec.

This supervisor is typically used to provide power-on reset (POR) monitoring and protection in a variety of applications, including microcontrollers, FPGAs, ASICs, and other components in systems operating on two supply system. With its two-input, single output pin design, the MAX6314US26D4+T can be used to ensure the safety and performance of industrial and automotive systems as it offers reliable and robust monitoring of voltage supply levels, as well as reset and enable signals.

The working principle of the MAX6314US26D4+T is quite simple. It monitors the voltage levels of two separate supply voltages and compares the voltage levels to its factory-trimmed thresholds. If it detects a fault condition or any other fault condition, like a power supply undervoltage or overvoltage, the supervisor will generate a reset signal. It will then initiate a reset pulse and hold the active-low reset output low until the fault condition is cleared. Once the fault condition is cleared, the supervisor will then assert the active-low reset output and enable the system power.

The MAX6314US26D4+T is used in a wide range of applications that require reliable monitoring of two separate supply voltages, along with reset and enable signals. Some of these applications include communication systems, industrial instrumentation, computing systems, medical systems, automotive systems, power supplies, battery management systems and process equipment.

In conclusion, the MAX6314US26D4+T is a bi-supply supervisor that is specifically designed to provide reliable and robust monitoring of two separate supply voltages, along with reset and enable signals. Its low power consumption, wide operating range, and robust design make it well-suited for a variety of industrial, automotive, and other applications.
