PMICs or Power Management Integrated Circuits are essential components of electric and electronic devices. They control and manage the power consumption of the device and ensure that every component gets only what it needs. The NCP308MT120TBG is a member of the family of PMICs, specifically of theirs Supervisors category. This article aims to discuss the application field and working principle of this component.

NCP308MT120TBG is a Single Mode Reset Supervisor IC or SMRST IC. It is designed to protect embedded systems from undesired conditions such as over voltage, over current and excessive temperature. An SMRST IC is embedded in the system to monitor and respond to such fault conditions. You can also use it to enable system power-up or reset.

The NCP308MT120TBG has an operating temperature range of -40°C to +125°C and and a maximum input voltage of 16V. It also has an adjustable forced reset delay with a typical delay of 200ms. It supports two reset outputs, one with an active polarity of active-low and one with an active polarity of active-high. The NCP308MT120TBG can be used in a variety of applications including automotive, industrial and consumer electronics.

Now let us discuss the working principle of the NCP308MT120TBG. The component consists of three major sections: a voltage monitoring section, a reset circuitry and a delay circuitry. The voltage monitoring section is used to monitor input voltages and compare them to a preset threshold. If the input voltage is above or below the threshold, the component will issue a reset signal.

The reset circuitry consists of an open-drain output transistor, which is used to create an active-low reset signal. The delay circuitry is used to delay the reset signal so that the device can be reset even after the fault condition has been corrected. The delay can be adjusted by setting the delay required for the application.

The NCP308MT120TBG is a powerful and versatile PMIC with a wide range of application areas. It provides reliable protection against overvoltage, overcurrent and high temperature conditions. The component also offers a variety of options for reset delay and reset polarity.

The NCP308MT120TBG is thus a great choice for applications requiring reliable and comprehensive power management solutions. The component is easy to integrate and works reliably even in the harshest of operating conditions.
