The ON Semiconductor NCP81075MNTXG is a high-performance, dual MOSFET driver designed to accommodate a wide range of power applications. This driver is specifically engineered to provide efficient and reliable operation for synchronous buck power stages, making it an ideal choice for computing, telecommunication, and consumer electronics where power efficiency is crucial.

Key Features

• High Drive Capability: The NCP81075MNTXG boasts a robust drive strength, capable of delivering peak currents of up to 4A for the high-side and low-side MOSFETs, ensuring rapid charging and discharging of gate capacitance for fast switching performance.
• Adaptive Dead Time Control: This feature automatically adjusts the dead time between the high-side and low-side drivers to optimize efficiency and prevent cross-conduction, which can lead to reduced power loss and improved system reliability.
• Tri-State PWM Input: The driver supports tri-state PWM input, allowing for a simple interface with the controller and providing a shutdown feature that reduces power consumption when not in active operation.
• Wide Supply Voltage Range: Operating from a supply voltage ranging from 4.5V to 18V, the NCP81075MNTXG is versatile and can be used in various systems without the need for additional voltage regulation components.
• Under-Voltage Lockout (UVLO): Both the high-side and low-side drivers have UVLO protection to ensure the device operates only when the supply voltage is sufficient, thereby protecting the MOSFETs from insufficient gate voltage.
