Introduction of MAX6865UK28D3S+T

MAX6865UK28D3S+T is an advanced supervisor device with under-voltage lockout (UVLO) and programmable adjustable watchdog timer functions which are designed to prevent system faults from leading to unexpected system reset or system failure. It is mainly used in the field of PMIC - Supervisors and fits into any system which requires advanced power management and regulation.

Features of MAX6865UK28D3S+T

Maxim\'s MAX6865UK28D3S+T is a supervisor device that provides a lot of features such as:

• Voltage monitoring and adjustable brown-out detection
• Programmable, adjustable watchdog timer (WDT) with reset pulse width from 1µs to 1.5s
• Dual, non-volatile WDT reload triggers, manual WDT reset and load detect
• Under-voltage lockout (UVLO) and programmable UVLO hysteresis
• Low current consumption and operating range
• Configurable push-pull and open-drain reset output options
• Wide O/P voltage range of 0.8V to 14V with very fast transient response
• Temperature Sense Output (TSO) with selectable threshold levels
• Energy saver mode and EMI grounding pads functionality

Application Field of MAX6865UK28D3S+T

Given the features of MAX6865UK28D3S+T, the device is suitable for the broad field of power management and regulation. It can be used as a supervisor in PMIC - Supervisors application as its programmable adjustable watchdog timer features can help to identify, isolate and prevent any system faults. It is also applicable for some industrial applications such as computer, gaming and communications applications. It is especially useful for system with fast core levels and transistor cycling, thanks to its very fast transient response which offers accurate and reliable performance in rapid signal transitions.

Working Principle of MAX6865UK28D3S+T

Essentially, the MAX6865UK28D3S+T works as an interface between the power source, such as a battery, and the power management circuit. It monitors the voltage level of the power source and will take action if the voltage drops below the specified level. In the event that the power source voltage goes below the specified voltage, the MAX6865UK28D3S+T will trigger an interrupt to the power management circuit. This interrupt allows the power management circuit to take the appropriate action to reduce the power drain from the battery or power source. The MAX6865UK28D3S+T also features a programmable adjustable watchdog timer which can be used to detect system faults and can be set to reset the system if the voltage from the power source drops below the specified level. The MAX6865UK28D3S+T also features a non-volatile Reload Trigger which is used to detect external events and force a system reset. In addition, the MAX6865UK28D3S+T also features configurable push-pull and open-drain reset output options and temperature sense output with selectable threshold levels.

Conclusion

In conclusion, the MAX6865UK28D3S+T is an advanced supervisor device that is suitable for applications in the field of PMIC - Supervisors. It is a sophisticated power management and regulation device that provides voltage monitoring, adjustable brown-out detection and programmable adjustable watchdog timer functions. The MAX6865UK28D3S+T also provides dual, non-volatile WDT reload triggers, manual WDT reset and load detect functions. It offers low current consumption and operating range and is suitable for some industrial applications such as computer, gaming and communications applications. The MAX6865UK28D3S+T also features configurable push-pull and open-drain reset output options and temperature sense output with selectable threshold levels.
