UCC27200DRG4 is an ultra-low quiescent current, high-current gate drive enhanced with diagnostic and protection functions. It is especially suitable for Class D audio amplifiers and motor control applications. It is one of the most comprehensive gate drive ICs on the market and offers a variety of features and advantages for designers, such as wide supply voltage ranging from 5V to 38V and adjustable dead time.
This device is part of the popular family of Power Management Integrated Circuit (PMIC) gate drivers, which provide a single integrated solution for various power management & control needs. Gate drivers are used to provide high current drive to the gate of power switching elements such as MOSFETs or IGBTs in order to switch on/off the power supply to a load. In addition, gate drivers provide diagnostic and protection functions to ensure reliable operation over time and under fault conditions.
 UCC27200DRG4 gate drive features include an integrated pre-driver stage providing an adjustable dead time and respond quickly to changes in the gate voltage, allowing for smooth gate transitions and improved efficiency. It also offers optimized short-circuit protection with both current limit and voltage limit protection to protect the device from over-current conditions. To improve its protection from current surge, UCC27200DRG4 also has an extended sense resistor for current sensing. The device also has the option to enable a low threshold shutdown feature, which helps in improving efficiency by turning off the current drive when the sensed current is below the configured threshold.
 
The device integrates a built-in comparator, a drive voltage measurement output, diagnostic LED, and an open drain low side fault output pin so that the designer can easily monitor the operational state of the device. This allows the machine designer to have more control and confidence in the performance, safety, and reliability of the machine. The device is offered in a compact 8 lead 3x2mm package with all of the above features and functions, making it suitable and convenient for space-constrained applications.
 
In summary, UCC27200DRG4 is one of the most comprehensive and advanced gate drive ICs available, offering a wide range of features and advantages that make it suitable for use in a variety of applications, from motor control to Class D audio amplifiers. With its wide supply voltage, adjustable dead time, integrated diagnostics, and protection functions, UCC27200DRG4 is an ideal solution for designers looking for an all-in-one gate drive solution.
