The MAX6313UK26D1-T is a three-pin power-supply supervisor and reset controller, specifically designed to provide all the features needed to monitor and control microprocessor-based system power-up and power-down operations without sacrificing time delay control. It provides a 1.5V reference voltage for resetting and supervising the reset, power-good functions for detecting the power supply, as well as monitoring and controlling system voltage. The MAX6313UK26D1-T is designed to provide all the features necessary to monitor and control microprocessor-based system power-up and power-down operations in a single device.

The MAX6313UK26D1-T is a three-pin Power Management Integrated Circuit (PMIC – Supervisors) from Maxim Integrated. It consists of both a reset circuit and a voltage monitoring circuit. The reset circuit is responsible for resetting the system on power up, and then maintaining the system in reset until the power supply is valid. The voltage monitoring circuit provides a 1.5V reference voltage over a range of voltages, which is used for resetting and supervising the reset, power-good functions for detecting the power supply, as well as monitoring and controlling system voltage.

The MAX6313UK26D1-Tsupervisor operates from any standard Vcc input voltage, ranging from 4.2V to 5.5V, and provides an accurate 0.1V hysteresis. It has an active-low reset signal whenever the Vcc falls below 1.7V and the power-good signal is below 1.5V. The reset signal is released when the Vcc reaches 1.9V and the power-good signal is above 1.7V. The MAX6313UK26D1-T supervisor also features an adjustable reset delay that allows the user to set the accurate reset release time.

The MAX6313UK26D1-T supervisors can be used in a wide range of applications including power- on reset and power-good functions for microprocessor-based systems, PCs, POS terminals, consumer electronics, embedded controllers, industrial controls, and other industrial and consumer applications. It can be applied to all types of microcontrollers with open-drain reset pins and other microprocessor-based systems.

Further, the MAX6313UK26D1-T supervisor offers an additional supply-voltage monitor input for reporting on the condition of any power supply connected to the V battery. It also offers a power-fail input for monitoring manual reset, power-on-reset, or other power-fail events. An active-low chip reset output is available for driving the microcontroller or logic-system reset pins, and it is also possible to cascade multiple supervisors.

In addition, the MAX6313UK26D1-T supervisor features an open-drain output that can be used to drive an ICs-reset pin directly. This makes it suitable for applications where the reset circuit is not directly connected to the chip reset pin, or where an indication of reset is required. The output is active low and can be used for driving the microcontroller or logic system reset pins.

The MAX6313UK26D1-T supervisor is a complete power-supply and reset controller device, providing all the features necessary to accurately monitor and control the power-up and power-down operations of a microprocessor-based system. It offers both a reset circuit and a voltage-monitoring circuit for monitoring the condition of any power supply connected to the Vbattery. The reset circuit maintains the system in reset until the power supply is valid, and the voltage-monitoring circuit provides a 1.5V reference voltage for resetting and supervising the reset, power-good functions, as well as monitoring and controlling system voltage. It is easy to use and is suitable for a wide variety of applications, including power-on reset and power-good functions for microprocessor-based systems.
