Introduction

MAX699CWE, or simply the MAX699, is a voltage supervisor integrated chip manufactured by Maxim Integrated Products. It is a member of the Voltage Supervisors family, aimed to provide system design engineers with a tool to monitor the power supply in electronic systems. This supervisor monitors the power supply voltage and triggers a time-delayed reset output if the voltage connected to it is too low or too high, or if it falls below a certain transverse voltage. Additionally, it provides a window detector, ideal for monitoring a regulated supply and detecting an over voltage condition.

Application Field

MAX699CWE integrated circuits can be used for a wide variety of application fields, for instance, in digital and analog systems, telecommunications, personal computers, laptop computers, industrial computers and many other applications. They are typically used in microprocessor-based systems, as a reset generator and watchdog timer, to prevent out of control conditions from occurring due to power supply faults.MAX699CWE provides a variety of features tailored to meet specific system requirements. It includes selectable time delay and reset threshold voltages, as well as open drain/open collector/ push-pull reset output options; selectable reset active conditions; a timeout reset and adjustable thresholds. Furthermore, MAX699CWE combines low quiescent current and fast reset response time with an ultra-low leakage transistor and excellent reset accuracy- ideal features that enable designers to squeeze the best performance out of their power supply designs.

Working Principle

The MAX699CWE is designed to monitor the voltage of the power supply. It is pre-programmed with specific safe thresholds, which will be compared to the voltage present in the power supply when it is connected. If the power supply voltage goes beyond the pre-programmed thresholds, the MAX699CWE will respond by resetting the power supply. The chip is equipped with a so-called window detector. It enables the circuit to monitor two different voltages, below and above the nominal range, which can be set separately for each window. In both cases, the MAX699CWE will respond by resetting the power supply if the monitored voltage exceeds the programmed thresholds.The MAX699CWE won\'t trigger any response if there is no problem detected in the incoming voltage. This feature is known as "watchdog timer", it safeguards against any out-of-control conditions, like sudden power down of the supply, by activating the reset feature when needed.The MAX699CWE integrates a time delay function that allows the time-delay between the voltage reaching the threshold and the reset action triggered on the output. This adjustable time-delay helps avoid false resets in transient conditions by providing a window of time to set-up a functional voltage level on the output before resetting the power supply.

Conclusion

The MAX699CWE is a versatile and reliable supervisor integrated circuit. It is designed to monitor the voltage of the power supply and trigger a reset if the voltage exceeds its pre-programmed thresholds. It provides a window detector and adjustable time delays between the detection of the threshold and the triggered reset. It is an ideal choice for system designers who want to make sure their systems are protected from any power supply fault or out-of-control conditions.
