MAX6855UK24D1+T

The MAX6855UK24D1+T is a voltage Supervisor and System Reset IC from Maxim Integrated. It is a single or dual voltage supervisor that provides accurate supervision of power-supply voltages from the primary and secondary rails of an embedded system. It features a analog-controlled voltage level detector and a low power-on reset (POR) function with a <2ms reset response time. The device provides supervisory reset and watchdog functions in embedded systems as well as supporting a range of preconfigured system reset Fault thresholds. An on-chip noise filter ensures that the reset signals remain stable during power-on and power-off transitions.

The MAX6855UK24D1+T is designed for power-supply supervisors and reset controllers in embedded systems such as instrumentation systems, communications systems, industrial systems, and computer systems. It is a general-purpose power-supply supervisor that provides stable power-on reset and power-off reset, watchdog timer, and voltage level detector with noise immunity. The device offers numerous power-supply voltage supervisor functions and flexible reset-and-timer functions, which enables developers to quickly and easily configure their system designs.

The MAX6855UK24D1+T is built with a wide range of features that make it a robust power-supply supervisor solution. It features a low-power logic circuit, a reset/timer logic circuit, and a noise filter that provides good signal integrity. It supports active-low, active-high, and auto-clear asserts and de-asserts on the reset signal. In addition, the device includes an on-chip temperature sensor for reducing the resistor count and improving the accuracy of reset-voltage management.

The MAX6855UK24D1+T works on the principle of voltage-level detection. This technology enables the device to monitor regulated power-supply voltages of a system and provide an output in case of any deviation from the pre-determined level. The voltage-level detector works by comparing the regulated voltage level against a reference voltage. If the regulated voltage falls below a certain level, the voltage-level detector asserts a reset signal, which alerts the system that there is a fault. The voltage level detector is programmable, so the user can configure the system to ensure that the reset signal is generated based on their specific requirements.

The MAX6855UK24D1+T also integrates a watchdog timer (WDT), which is designed to detect and initiate system reset when it passes the timeout period. The WDT triggers a reset signal whenever it detects an error or when an input signal fails to respond. The watchdog timer allows the system to recover from software and hardware faults, as well as external events such as power interruption or system reset. The WDT can be configured in various timeout periods, which can be adjusted to suit various applications.

The MAX6855UK24D1+T is a highly flexible and reliable power-supply supervisor solution. It has built-in voltage-level detection and watchdog timer functions, as well as an on-chip temperature sensor, making it an ideal solution for use in embedded systems such as industrial automation and control systems, energy-management systems, and consumer applications. Additionally, the device is available in a wide range of package sizes and varieties, making it more cost-effective.
