UCC27512DRST Datasheet/PDFThe UCC27512DRST is a monolithic integrated circuit that includes a high–speed gate driver with adaptive shoot–through (ATS) prevention and an output buffer. It is specially designed for driving N–channel MOSFETs, IGBTs and SiC MOSFETs used in power converters such as the buck, boost, fly–back, forward converters and push–pull topologies. The UCC27512DRST is designed with an adaptive shoot–through (ATS) prevention and overlap protection to ensure safe operation of the MOSFETs and IGBTs.
Application Field
The UCC27512DRST is suitable for use in applications such as solar, building automation, motor control, communication systems, consumer electronics, and automotive applications. The UCC27512DRST gate driver works in applications including buck, boost, fly–back, forward converters and push–pull topologies. In power systems, this device can drive the power semiconductors used in high frequency DC/DC circuits, AC/DC converters, hard switching converters and complete power supply systems. As these drivers offer precise control and adjustability, they can be used to improve efficiency, reduce noise and minimize electromagnetic interference in power systems.
Working Principle
The UCC27512DRST gate driver works in a wide range of switching frequencies from 10kHz to 700kHz, and is suitable for use with both single-ended and differential inputs. Its wide input voltage range makes it suitable for use in applications with widely varying input conditions. This device offers a precise, current-limited and temperature compensated slope for reducing ringing and for improving switching margins.
The UCC27512DRST gate driver integrates an adjustable current and voltage regulation circuit. The current clamping function limits the gate current to a user-defined level, which helps ensure that the MOSFETs and IGBTs remain safe during shoot–through and overlap conditions. This device also features an adjustable dead time and pre-driver delays, offering adjustable rise and fall times that provide optimal operation for hard switching applications.
The UCC27512DRST gate driver is also capable of operating in continuous conduction mode (CCM), which helps to reduce switching losses and promotes improved power system efficiency. This device provides comprehensive protection for the drivers, including undervoltage lockout, overtemperature protection, gate output over-voltage protection, gate output overcurrent protection, and dead time overrun protection.
The UCC27512DRST gate driver is an ultra low-power, high-speed, industrial-grade device that is ideal for use in high power system applications. It offers a high degree of adjustability and flexibility, and provides power and noise reduction features to ensure efficient and reliable operation of the system.
