The MAX6855UK26D5+T is a robust, precision-regulated system reset supervisor from Maxim Integrated. It is designed for use in battery powered systems and is ideally suited for applications that require fast and reliable board reset when power is lost. This product is also a member of the family of Supervisors from Maxim Integrated, which provides users with superior accuracy, noise immunity and higher reliability.

The MAX6855UK26D5+T has several features which set it apart from other reset supervisors in its class. It features an ultra-wide 5V+/-5V operating voltage range, low power consumption, low thermal shutdown temperature and virtually no hold up time. It monitors both system power and reset inputs, allowing it to reset the board in the event of a power loss or inactivity due to software failure. In addition, it provides both active-high and active-low power on reset and pushbutton reset capability. It also features an integrated watchdog timer, which can be configured to reset the system in case of a software lock-up.

In terms of application field, the MAX6855UK26D5+T is typically used in systems such as those found in medical and industrial environments where continuous system performance and reliability are essential. It can also be used in game consoles, servers, routers and other high-performance applications where board reset is desired.

As for its working principle, the MAX6855UK26D5+T has two independent channels to monitor both system power and reset input. When the voltage on one of the channels drops below a preset threshold, a power-on reset is generated and the system is restarted accordingly. In addition, the onboard watchdog timer is configured to generate a reset signal in case of software lock-up, preventing the system from becoming unresponsive. The supervisor is also capable of detecting power and reset inputs independently, allowing it to detect board reset and generate a power on reset even when the system is idle or inactivity.

In summary, the MAX6855UK26D5+T is an ideal choice for use in battery powered systems and applications that require fast and reliable board reset when power is lost. It features an ultra-wide operating voltage range, low power consumption, low thermal shutdown temperature and virtually no hold up time, as well as active-high and active-low power on reset and pushbutton reset capability. Furthermore, its integrated watchdog timer makes it capable of resetting the system in case of a software lock up.
