MAX6383XR24D2-T

The MAX6383XR24D2-T is a member of the MAX®638 supervisory family. Mainly used for monitoring the power supply and resetting its circuits, So MAX6383XR24D2-T is classified in the PMIC – Supervisors type.

Application Field

The MAX6383XR24D2-T is designed to monitor the voltage supply in a wide variety of applications. This device can be used with voltages ranging from 2.5V to 5.5V in ATXPC systems to monitor the 5V and 3.3V power rails, as well as other critical voltages. It is also well suited for powering Flash memories in applications where the power supply must be reset in the event of power-related malfunction.

The MAX6383XR24D2-T is also designed to be used in other applications, such as mobile devices, video cameras, digital media players, signal processing cards and network adapters. Due to its low quiescent current, small package size, low power consumption and low power supply noise immunity, it is especially suitable for handheld equipment.

Working Principle

The MAX6383XR24D2-T’s main function is to provide control and reset signals for systems when power supplies get out of their specified range. It has a built-in comparator and a reset generator with a reset threshold voltage range from 2.37V to 5.5V.

When the input voltage reaches the reset threshold voltage, and then the reset signal is triggered and held active until the input voltage returns to a safe margin below the threshold. This reset signal is then used to re-initialize the system.

The MAX6383XR24D2-T also features an adjustable timeout period to define the minimum reset pulse width. It also provides an active-high power-good (PG) output signal to indicate that the power supply voltage is within a specified range. The MAX6383XR24D2-T also has a bidirectional, push-pull open-drain reset output.

Additionally, the MAX6383XR24D2-T features a programmable frequency range from 250 kHz to 8.7 MHz, which is used to delay the start of a reset, as well as detect power supply noise. This allows the MAX6383XR24D2-T to ensure all power supplies have settled before resetting the system, and also helps to prevent resetting caused by transient noise on the power supply line.

Conclusion

The MAX6383XR24D2-T is a supervisory device suitable for a variety of applications. Features such as adjustable reset threshold voltage, reset delay, power-good output, and programmable frequency range allow it to provide robust, reliable voltage monitoring and reset control. It is well suited for use in ATXPC systems, mobile devices, video cameras, digital media players and network adapters.
