The MAX6457UKD0C+T is a feature-rich supervisor typically used in industrial, consumer and portable electronics applications. It is a low-cost, mid-voltage, sub-nanosecond supervisor which is optimized for visibility, stability, and flexibility. This article will focus on the application field and working principle of MAX6457UKD0C+T.

Application Field

The MAX6457UKD0C+T supervisory circuit can monitor multiple power supply voltages and supply a reset output to maintain system integrity in industrial, consumer and portable electronics applications. This circuit includes an adjustable Watchdog Timer, voltage detector, and reset output timer to minimize system errors.

The MAX6457UKD0C+T supervisory circuit has a wide operating voltage range, from 3.0V to 18V. It provides high accuracy voltage detection with a +/-3% accuracy from 3.0V to 16V. It has a low-voltage lockout and reset generator circuit with an open-drain output signal, which provides an active-low reset when triggered by any one of the power supply voltages. It also has an adjustable Reset Output signal which delays system reset for up to 1.7 seconds. The MAX6457UKD0C+T supervisory circuit also includes an adjustable voltage watchdog timer which can be used to detect system fault condition.

The MAX6457UKD0C+T supervisory circuit is ideal for embedded applications such as powering microcontrollers, batteries, power supplies, and sensors. It also works well with systems that require reliable power-up sequencing, as well as systems that require fast power-down sequencing.

Working Principle

The MAX6457UKD0C+T supervisor works by monitoring multiple power supply voltages and detecting when one of the power supply voltages has dropped below the fault threshold. When any one of the power supply voltages has dropped below the fault threshold, the MAX6457UKD0C+T supervisor will generate an active-low reset signal which will reset the system. The Reset Output signal is adjustable and can be programmed to generate a reset signal for up to 1.7 seconds.

In addition to resetting the system when a fault is detected, the MAX6457UKD0C+T supervisor also includes a voltage watchdog timer. This timer can be used to detect and generate a reset signal if the system stops responding or is not running correctly. The watchdog timer can be programmed to generate reset signals for up to 1.7 seconds.

The MAX6457UKD0C+T supervisor is designed to be simple and reliable. It is designed to be used in systems that require reliable power-up sequencing, as well as systems that require fast power-down sequencing. It is a low-cost, mid-voltage, sub-nanosecond supervisor which is optimized for visibility, stability, and flexibility.

In summary, the MAX6457UKD0C+T supervisor is a feature-rich device ideally suited for industrial, consumer, and portable electronics applications. The MAX6457UKD0C+T supervisor can monitor multiple power supply voltages and supply a reset output to maintain system integrity. It also includes an adjustable voltage watchdog timer which can be used to detect system fault condition and generate reset signals. The MAX6457UKD0C+T supervisor is designed to be simple and reliable and can be used in systems that require reliable power-up sequencing, as well as systems that require fast power-down sequencing.
