Gate Drivers ICs

The Texas Instruments UCC27321DR is a high-voltage, high-power gate driver with integrated bootstrap diode and high-side and low-side gate driver channels. It is designed for use in power electronic applications such as motor drives, power supplies, and renewable energy systems.

Description:

The UCC27321DR is a monolithic integrated circuit that provides two high-voltage gate driver channels with integrated high-side and low-side gate drive. The device is designed to drive power MOSFETs and IGBTs with voltage ratings up to 900V. The high-side gate driver channel features a bootstrap diode and a charge pump to supply the necessary voltage for driving the high-side gate of an IGBT or MOSFET. The low-side gate driver channel provides independent control of the low-side gate.

Features:

• High-voltage operation up to 900V
• Integrated high-side and low-side gate driver channels
• Integrated bootstrap diode for high-side gate drive
• Independent control of high-side and low-side gate drive
• Wide supply voltage range (10V to 60V)
• Short circuit and overcurrent protection
• Undervoltage lockout
• Thermal shutdown protection
• Small package size (5mm x 7mm)

Applications:

• Motor drives for industrial and automotive applications
• Power supplies for telecom and computing equipment
• Renewable energy systems such as solar inverters and wind turbine converters
• Battery charging systems for electric vehicles and energy storage systems
• High-power DC-DC converters

Overall, the UCC27321DR is a versatile and high-performance gate driver that can be used in a wide range of power electronic applications. Its integrated features and robust protection functions make it a reliable choice for demanding applications that require high-voltage and high-power operation.
