The NCP308MT090TBG is a tiny, low power microcontroller special reset supervisor circuit that offers advanced reset functionalities for microcontrollers and digital signal processing circuits. It is classified under PMIC (Power Management IC) supervisors. This particular supervisor provides both short-circuit protection and tamper sensing with a configurable reset timer output.

The NCP308MT090TBG is comprised of several semiconductor components, namely, two P-Channel MOSFETS, four Schottky Diodes, an N-Channel MOSFET, a voltage regulator, an 8-bit pulse-width modulation (PWM) timer, a temperature compensating voltage reference oscillator, and a temperature resistant circuit.

The NCP308MT090TBG is suitable to be used in various application fields related to microcontroller reset functions such as automotive, industrial and consumer electronics, medical, and aerospace. It is small, inexpensive and can be combined with other cooling and power supply components. It is also capable of controlling voltage with the use of two internal monitored reset outputs.

The main working principle of the NCP308MT090TBG is straightforward. Whenever the supply voltage drops below its preset trigger level, the supervisor trips and initiates a reset. This reset can be of either short-circuit protection or tamper sensing depending on the type of reset chosen. The startup time is configurable, depending on the user\'s needs.

The NCP308MT090TBG also has the capability to sense decreased power supply voltage at the supply pin. When the system power supply voltage is below a certain level, it will initiate the reset and de-activate any further operation, thus stopping the system from working. The temperature compensating voltage reference oscillator also has the capability to sense temperature levels and adjust the reset time accordingly, providing additional protection against any out-of-specification occurrences.

The pulse-width modulation (PWM) timer allows setting a resolution of up to 8 bits and an output refresh rate of up to 500 kHz. The timer can be used to create a wide range of different reset and timer outputs, enabling designers to fine tune the system’s reset behavior to their needs. The NCP308MT090TBG also includes a unique temperature-resistant circuit, allowing the supervisor to remain temperature, overload and short-circuit safe even at high temperatures.

The NCP308MT090TBG is an ideal solution for applications needing reliable reset control such as automotives, industrial, consumer electronics, medical and aerospace, due to its enhanced features and low cost. Its wide range of features, small size and low power consumption make the NCP308MT090TBG the perfect supervisor for microcontroller-based applications.
