MAX697CWE+T

MAX697CWE+T is a versatile dual voltage supervisor circuit specially designed for various electronic applications. It works through a reset pin that triggers the power resetting. The device provides both active-low and active-high reset outputs. It also provides a Power Good output pin that detects if the power supply is valid. The device is made up of several components, including a comparator, an internal reference, an oscillator, and control logic.

The device features a wide input voltage range of 1.8V to 12V, allowing it to be used in many types of electronic systems. This wide input range also provides a margin of safety when a system encounters a power fault. The device also features over-voltage, under-voltage, drop-out voltage, and power-on reset settings that give added protection against fault conditions. The device also has an adjustable reset timeout. This allows it to detect when a voltage level is not within an acceptable range and initiate a power reset.

The working principle of the MAX697CWE+T is based on its comparator, which compares the internal bandgap voltage to an external voltage reference. When the voltage drops below the set threshold, the active-low reset output is triggered. For a valid power up condition, the input voltage must exceed the threshold level by a certain amount, called the Power Valid Hysteresis, for a fixed amount of time, called the Reset Delay Time. This ensures that the power is stable before the reset output is cleared. When the power supply reaches the Power Good threshold, register the Power Good signal, which indicates the presence of a valid voltage.

The MAX697CWE+T is designed to be used as a safety device in many different applications. Its accuracy and reliability in detecting power supply irregularities make it suitable for use in critical applications such as those where preventive maintenance is not possible. Its low power consumption, wide input range, and adjustable settings make it suitable for applications where power savings is critical. It provides an adjustable reset timeout which enables the device to detect power failure conditions efficiently. Its compact size and ease of implementation also make it attractive to system designers.

The MAX697CWE+T is an efficient and reliable dual voltage supervisor circuit used in many types of electronic devices. Its wide input voltage range, adjustable reset timeout, and power good signals allow it to detect power irregularities and reset system when necessary. Its small size and low power consumption make it suitable for power-sensitive applications. Its accuracy and reliability make it a good choice for critical applications where preventive maintenance cannot be relied on.
