MAX6313UK40D4-T

Introduction

MAX6313UK40D4-T is a supervisor IC designed by Maxim Integrated.It is a highly integrated power management integrated circuit (PMIC) and belongs to the Supervisors category, intended for use in voltages and potentials in harsh operating environments. The MAX6313UK40D4-T combines various safety, monitoring, and control functions into a single device, providing flexible control for the system and reducing the design time & cost of the power application design.

Application fields

The MAX6313UK40D4-T is a 4-channel supervisor IC capable of sensing and monitoring a range of voltages and potentials. The four voltage input channels can be used to monitor different types of voltages and potentials including battery voltage, system voltage, power supply, or other system voltages for over and undervoltage conditions.

The MAX6313UK40D4-T is designed to be used in a variety of industrial and automotive applications, such as industrial control systems, automotive electronic systems, battery condition monitoring, automotive charging systems, and automotive systems.

As a supervisor IC, the MAX6313UK40D4-T is equipped with additional features to improve safety and security in applications. It provides an open-drain fault output that can be connected to other controllers or microcontrollers to directly indicate an overvoltage or undervoltage condition as well as a programmable latched/non-latched timer. It also incorporates ESD protection on the inputs.

Working principle

The MAX6313UK40D4-T compares each input voltage to the voltage-set thresholds and generates output signals accordingly. A hysteresis voltage can be added to the thresholds to provide additional protection from noise and false trips. The supervisor also provides a programmable latched/non-latched timer to prevent false triggers.

When an overvoltage or undervoltage condition is triggered on one of the input channels, the MAX6313UK40D4-T will generate an active low fault signal. This fault signal can be connected to other controllers or microcontrollers to directly indicate the trip condition. Additionally, the supervisor will also reset itself when the trip condition is removed.

The MAX6313UK40D4-T also features other features like a power-on reset (POR) output, which will generate a reset signal when the VDD voltage is below the POR threshold voltage. It also features a power-down reset (PDR) output, which will generate a reset signal whenever the VDD voltage is below the system voltage threshold. These reset signals can be used to reset microcontrollers or system controllers to avoid system failures.

Conclusion

The MAX6313UK40D4-T is a highly integrated and powerful supervisor IC, suitable for a variety of industrial and automotive applications. The IC is capable of sensing and monitoring different voltages and potentials, and can generate an active low fault output when an overvoltage or undervoltage condition is triggered. It also provides additional protection from noise and false trips with a hysteresis voltage and a programmable latched/non-latched timer. Finally, the IC provides additional features like a POR and PDR output to effectively reset microcontrollers and system controllers.
