Power management integrated circuit (PMIC) is an important component of modern electronic systems. The main purpose of a PMIC is to reduce power consumption in the circuits by controlling the voltage, current and temperature of the devices. The MAX6313UK28D1-T is a type of PMIC - Supervisors, which is used in a variety of applications. Let us take a look at its application field and working principle.

The MAX6313UK28D1-T is a single supply 1.8V to 5.5V micro-power voltage supervisor with push-pull output. It is mainly used in power systems, such as computers, telecommunication, motor control and automotive. It is suitable for systems that require low-cost and low-voltage monitoring solution. Its built-in reset circuitry provides an active-low reset to the system when the input voltage is lower than its threshold. It also includes low power supply current and power-up reset configuration.

The device is capable of monitoring up to four supply voltages using its four input pins. It has enable pin which allows the reset output to be enabled or disabled. The enable pin can be used to safely shut down a system without the need to power cycle it. This device also provides an active-low logic-level open-drain output.

The MAX6313UK28D1-T device has wide operating voltage range from 1.8V to 5.5V and provides an accurate reset threshold. It also provides low power supply current and provides up to 2.5mA of current drive at the reset outputs. It is packaged in a 6-pin SOT-23 package to provide a compact solution and requires only a few external components.

The MAX6313UK28D1-T is designed to monitor the voltage on the input pins and to provide a reset signal to the system when the voltage on the input pins is below the reset threshold. The output of the device is an active-low reset signal and it goes low when the monitored voltage is below the reset threshold for a certain amount of time. This time period is adjustable by an external capacitor. When the voltage on the input pins returns to its normal operating level, the reset output goes high, which is recognized by the system as active-high reset.

The MAX6313UK28D1-T also includes an enable pin, which allows the reset output to be disabled if desired. When the enable pin is high, the reset output is disabled and the input pins can be monitored. When the enable pin is low, the reset output is enabled and will go low if the voltage on the input pins is below the reset threshold. The reset output will stay low until the voltage rises above the reset threshold.

The device also has an output driver which can provide up to 2.5mA of current drive to the reset output. This current drive can be used to drive an LED, a relay or another device to indicate the status of the reset output. The current drive can also be used to drive a transistor or a MOSFET to control the power on and off of a system or load.

In summary, the MAX6313UK28D1-T is a single supply supervisor with wide operating voltage range which is suitable for various applications. It is a very cost-effective solution for providing low-voltage monitoring and resetting capabilities for power systems. Its push-pull output and wide operating voltage range makes it a perfect solution for applications that require low power consumption.
