The NCP5111PG is a high-performance, high-voltage half-bridge driver manufactured by ON Semiconductor, designed to efficiently drive MOSFETs in a half-bridge configuration. This driver is particularly suitable for applications that require high-speed operation and efficient power management, such as switch-mode power supplies, motor controllers, and inverter circuits.

Key Features

• High Voltage Range: The NCP5111PG operates with a supply voltage up to 600V, making it suitable for a wide range of high-voltage applications.
• High Current Drive Capability: It can source up to 350 mA and sink up to 650 mA, providing robust drive capability for the power MOSFETs.
• Dual Independent Inputs: With separate logic inputs for the high-side and low-side drivers, it offers flexibility and precise control over the switching actions.
• Under-Voltage Lockout (UVLO): The UVLO feature ensures that the device operates only when the supply voltage is sufficient, thereby protecting the MOSFETs from insufficient gate voltage.
• Matched Propagation Delays: This characteristic ensures better control and efficiency by providing symmetrical operation of the high-side and low-side drivers.
• Cross-Conduction Prevention: The built-in dead-time insertion helps to prevent shoot-through by ensuring that both high-side and low-side MOSFETs are not on simultaneously.
• Extended Temperature Range: The NCP5111PG is designed to operate over an extended temperature range, making it suitable for industrial applications.
