UCC27326DGNR is a versatile IGBT/MOSFET gate driver designed to offer superior performance in motor drive applications. It integrates a PWM desaturation logic and high-side and low-side gate driver modules, and has an ultra-fast switching speed, small size, and extremely low-cost package for easy integration in motor drive applications.

This gate driver provides two driving outputs, one for high-side and one for low-side with built-in desaturation logic to keep the gate driver from false triggering. It provides a high-side gate-driving current of 5A and can handle input voltage up to 24V. The device also integrates thermal protection, gate voltage common-mode protection, and under-voltage lockout protection.

The UCC27326DGNR is a perfect device for motor control applications such as hard disk drives, air conditioners, and brushless motor drivers as it offers several benefits over other gate drivers such as very fast switching time, low package profile and cost, and support for various IGBT and MOSFET configurations.

It uses a unique voltage driven pulse width optimized high fixed turn-on and constant turn-off current values for a given temperature. The desaturation logic in the device prevents excessive current from entering the gate drivers, thus avoiding false triggering due to the heavy pull-up and pull-down currents through the gate circuit when the gate voltage is applied and removed from the gate.

The device can operate in Arduino, 3.3V and 5V logic, making it highly compatible with most of the common logic. The high-low side desaturation logic can be used to detect and react to excessive current conditions in the gate driver circuit, and provide PWM control to keep the output drive current consistent, thus avoiding false triggering. The device also has fixed turn-on and turn-off times, and can be used to drive a wide variety of IGBT and MOSFET devices.

The UCC27325DGNR application field include drives applications such as heating, ventilation, and air conditioning, industrial and automotive motor drives, brushless DC motor speed controllers, hard disk drives and 3-phase generators. It is ideal for applications where high performance and high reliability are essential, as it is not only compatible with the most common logic, but also provides an extremely fast switching time, small package size, good thermal protection and low gate voltage common-mode protection.

In conclusion, the UCC27325DGNR is an ultra-fast and versatile gate driver, perfect for applications where performance, reliability, and cost are essential. It is equipped with desaturation logic and features a low-power amplifier and high-side and low-side switching outputs. With its small size, fast switching time, and protection features, it provides an ideal solution for motor control applications such as hard disk drives, air conditioners, and brushless motor drivers.
