NCP81255MNTXG

The NCP81255MNTXG is a device used in a variety of applications, providing voltage regulation and protection in a variety of settings. It is a special purpose voltage regulator, used to convert unregulated or large AC input voltages into stabilized DC outputs. It is used in various settings such as automotive, computer, telecommunications, and consumer electronics applications.The NCP81255MNTXG is designed with a wide range of comprehensive protection features that maintain the device from current and thermal overloads, output disconnection, low-power status, and voltage irregularities. Its integrated gate driver and low gate charge significantly reduce the complexity of designing with MOSFETs, providing high efficiency and low switching losses. The NCP81255MNTXG is designed to reduce the power dissipation of both switching and linear regulators, providing a solution for improved efficiency, in addition to the protection of the load circuitry. Controlled via an external pulse-width modulation (PWM) signal or an analog voltage, it enables the integration of digital power management functions such as electronic load sensing, voltage and current regulation, and power-saving features.The NCP81255MNTXG offers two high-side gate drivers and two low-side gate drivers, each with 4A peak current integrated MOSFETs. It is designed with a wide-range of product features such as a controlled in-rush current start-up feature, Auto-Restart, low-power Standby mode, Smart Power Save feature, and integrated dead-time for balanced power transfer. As a special purpose voltage regulator, the NCP81255MNTXG operates in three basic power modes, which can change from an idle state to a power good state as required. These three power modes: Active Mode, Standby Mode, and Low Power Mode. Each mode provides its own distinct voltage regulation scheme and behavior that can be adjusted by device configurations.In Active Mode, the NCP81255MNTXG operates in a normal fashion, balancing the load currents and providing the required output voltage.Standby Mode reduces the device’s quiescent power. In standby mode, the output voltage is regulated to a user-defined value by either PWM or measured voltage input. This can help to decrease power consumption, prevent overloaded voltage applications, and reduce EMI.In Low Power Mode, the NCP81255MNTXG regulates the output to a low voltage, reducing power consumption further.The NCP81255MNTXG is a highly versatile and feature-rich solution for providing power management control. From protecting a load from voltage irregularities to helping designers implement applications that are efficient and robust, the NCP81255MNTXG is an ideal device for many applications.
