NCP5901GMNTBG Application Field and Working Principle PMIC – Gate Drivers are a type of power management integrated circuits (PMICs) found in Proportional–Integral–Derivative (PID) controllers and many other electronic circuits. These circuit drivers are used to drive electronic gates, such as MOSFETs, to change the output voltage or current of a circuit.The NCP5901GMNTBG is a feature-rich, single-channel, low-voltage, high-efficiency gate driver IC developed by ON Semiconductor. The device provides active low or high output in combination with an adjustable slew rate of the output transition and an adjustable timing for the deadtime protection overcurrent protection, and up to 7.5A peak current capacity. In addition, the NCP5901GMNTBG provides an adjustable, programmable switching frequency nearly ranging from 100kHz to 1MHz and over temperature protection, making it suitable for the majority of general-purpose motor drive applications.The NCP5901GMNTBG has widespread application fields, such as industrial automation, motor control, robotics, and consumer and entertainment applications in which the output switching needs to be fast and efficient. This chip also represents an ideal solution for general-purpose power supplies and DC-DC converters in applications such as spacecraft, solar inverters, hobbyist equipment, and power management systems.To determine and explain the working principle of the NCP5901GMNTBG, we need to understand two of its key features. Firstly, the NCP5901GMNTBG utilizes its programmable switching frequency with a configurable PWM to provide the output voltage or current. Secondly, the NCP5901GMNTBG has two internal oscillators, which together provide feedback and adjust the frequency of the output pulse, allowing for precise control over the output voltage or current levels.When the device is powered up and the voltage at the inputted gate is zero, the output driver will be active and a certain amount of current will be drawn from the source. This current causes the device to turn on the internal oscillator, and a pulse of voltage is transmitted from the source to the output driver. This output pulse is then used as an input for the second oscillator, and its frequency is adjusted accordingly. The pulse width modulation also determines the output voltage or current levels based on the input voltage rate.In conclusion, the NCP5901GMNTBG is a low-voltage, high-efficiency gate driver IC which can be used to drive electronic gates, such as MOSFETs, to change the output voltage or current of a circuit. The device has wide application fields and its working principles relies on configurable PWM and two integrated oscillators.
