A supervisor or supervisory control refers to a type of circuit within a power management integrated circuit (PMIC) that is used to accurately monitor and manage the power of other circuits. The MAX6466UR23+T is an ultra-micro power monitoring supervisor that fails-safe under the most extreme fault and delay conditions. Despite its small size, it offers sophisticated functionality and is applicable in a wide range of systems and applications.

The MAX6466UR23+T is a low-voltage, low-power supervisor. It includes a reset output, which indicates when the monitored voltage drops below an adjustable threshold voltage. It also features an externally adjustable watchdog timeout interval from 7.5 ms to 500 ms. This feature can be used to keep systems from becoming unresponsive.

A unique feature of the MAX6466UR23+T is its advanced reset sequencing. This feature allows the supervisor to start the power-on reset in an orderly fashion and thereby eliminate unpredictable system startup due to improper control of power. This can prevent system instability due to improper power sequencing.

The MAX6466UR23+T can also talk to other components in the system, including other supervisors, via its open-drain output pin. This communication capability helps ensure that system components are maintained in an optimal state despite power cycles. Additionally, it has an active-low reset output, which provides an easy-to-use interface for other components in the system.

The MAX6466UR23+T is an ideal supervisor for applications requiring higher reliability and/or precise timing. Because of its small size, it can be used in a variety of wireless communications and medical-related applications, such as wireless medical devices. It can also be used in combination with other power management ICs to provide precise and efficient power control.

The working principle of the MAX6466UR23+T power monitoring supervisor is quite simple. It constantly monitors the main power supply voltage. Once the monitored voltage drops below an adjustable threshold voltage, it generates a reset output to indicate the power supply volatge has dropped below the threshold voltage. Additionally, it has an externally adjustable watchdog timeout interval, which can be used to prevent systems from becoming unresponsive due to lack of power.

In summary, the MAX6466UR23+T power monitoring supervisor is an ultra-micro power monitoring device that is intended for use in a wide range of systems and applications. Its features include advanced reset sequencing, open-drain output pin for communication with other devices in the system, and active-low reset output for easy interface with other components. It operates by constantly monitoring the power supply voltage and generating a reset output when the monitored voltage drops below an adjustable threshold voltage.
