Power Management Integrated Circuits (PMICs) are among the most important integrated circuits (ICs). PMICs are designed to control and manage the power supply of one or more components on a board or within a system. Supervisory circuits, also referred to as supervisors, play a significant role in PMICs. Supervisors provide functions such as reset systems and under-voltage detection which ensure that a device is operating within its expected power specifications. The MAX809JEUR+T is a great example of a supervisor IC.

The MAX809JEUR+T is a versatile supervisor IC with a wide range of applications. It is a precision reset IC that is specifically designed for applications requiring accurate power-on reset assurance. This IC monitors both the positive and negative rails of a power supply, providing a predictable reset behaviors for different voltage conditions. The IC also features configurable reset threshold levels and reset pulse widths. This provides flexibility in defining the power-on reset characteristics for different systems.

The MAX809JEUR+T is designed to operate with a wide range of supply voltages, typically between 2.5V and 5.1V. It is well-suited for use in low voltage systems, while its detection accuracies are maintained even in noisy power supply conditions. The IC is available in a variety of package types, including SOIC, QFN, and SOT packages, allowing it to be used in a variety of applications. It also features a high reliability core reset for increased reliability.

The working principle of the MAX809JEUR+T is simple. It uses two comparators to monitor the input voltage. When the input voltage falls below the reset threshold level, the comparator will trigger a reset signal. The MAX809JEUR+T also has a timeout period that can be configured to determine how long the reset signal is held for. Additionally, the IC has open-drain input/output pins that make the IC compatible with most microprocessors and other peripheral devices.

In summary, the MAX809JEUR+T is a high performance supervisor IC that can be used in a wide variety of applications. It is designed to operate over a wide range of power supply voltages, while maintaining excellent accuracy and reliability. Furthermore, the IC features configurable reset threshold levels and reset pulse widths, making it adaptable to different system requirements. These features, combined with its small form factor, make the MAX809JEUR+T an ideal choice for power-on reset supervisors.
