MAX6423US46+T

Power management integrated circuits (PMICs) are devices used for managing power within a circuit. They are crucial components in today’s electronic systems, ensuring that components do not exceed their ratings and the system functions correctly. PMICs are divided into several categories, with each one focusing on a different aspect of power management. One type of PMIC is the supervisor, which provides system reset and power monitoring.

MAX6423US46+T is a microcontroller-based reset and supervisor circuit for monitoring system power for reliable operations in portable electronics and other applications. The MAX6423US46+T offers three voltage thresholds, a delay interval of up to 10 seconds, and a power-on reset (POR) delay of up to 3 seconds to ensure reliable system boot-up.

The MAX6423US46+T comes with a voltage supervisor circuit that monitors the power supply and provides reset signals to the microcontroller. This circuit is designed to provide longer time intervals with increased accuracy, thus ensuring the reliability and safety of the system. In addition, it has a selectable delay function to reduce system-level power transients that could cause the microcontroller to reset.

The MAX6423US46+T is ideal for use in power-sensitive systems such as portable electronics, machine tools, and automotive applications. Its versatile design and low power consumption make it suitable for a wide range of systems. For instance, in automotive applications, the MAX6423US46+T allows for manual reset functionality to control the reset times for various system modules.

The MAX6423US46+T features a selectable power on reset (POR) delay that can be used to provide a reset countdown timer. This feature allows the reset to occur when both the timer and the requisite condition are satisfied. This function is particularly useful in system designs where power transients may periodically occur, as it can provide a reliable system reset.

In addition, the MAX6423US46+T provides a status indication in the form of an LED indicator. This allows for remote monitoring of the system. This can be particularly useful for applications that require reliable operations, such as medical applications.

The MAX6423US46+T also features a 3-pin interface, which allows it to be used as a stand-alone reset controller. This feature allows the device to be used in applications where there is no microcontroller or other integrated circuit present.

In summary, the MAX6423US46+T is an ideal reset supervisor for power-sensitive systems requiring reliable operations. Its versatile design and low power consumption make it suitable for a wide range of applications. It comes with a selectable POR delay, status indication, and a 3-pin interface that allows it to be used as a stand-alone reset controller.
