Introduction

UCC5350MCD is a series of high voltage isolated gate drivers in small packages developed by Texas Instruments. The series is widely used in industrial, inverter and motor drive applications due to its high voltage isolation, wide operating temperature range and high common mode transient immunity. This driver is designed to drive MOSFETs, IGBTs and other discrete power switches in a wide range of inverters, motor controllers, solar converters, AC/DC and DC/DC converters.

Working principle

UCC5350MCD works by transferring power from the low side gate driver to the high side gate driver. The low side driver is a power transistor used to deliver power to the high side gate driver while the high side driver is a power MOSFET used to deliver power to the gate of the device. The high side driver has a built-in isolation system to maintain electrical isolation between the low and high side of the circuit.The low side gate driver is powered by a logic control signal (CCLK) from the microcontroller that is used to set the duty cycle, and a power current path signal (CF) from the microcontroller that is used to enable the conduction between the low and high side drivers. The high side driver is then driven by the combined signals and drives the IGBTs or MOSFETs in the system.

Application fields

UCC5350MCD is used in various types of high voltage applications. This includes motor drives, inverters, solar power converters, AC/DC and DC/DC converters, high power relays and switchgear. UCC5350MCD is ideal for motor drives and inverter applications due to its high voltage isolation and wide operating temperature range. It is also suitable for use in power electronics applications including high power relays and switchgear due to its high common mode transient immunity, which allows for a reliable control signal. UCC5350MCD can also be used in solar power converters, AC/DC and DC/DC converters due to its robust design, which ensures high efficiency performance.

Conclusion

UCC5350MCD is an isolated gate driver designed to drive IGBTs, MOSFETs and other power switches in various inverters, motor drives and solar power converters. Its high voltage isolation, wide operating temperature range and high common mode transient immunity make it suitable for a wide range of applications. This series can be used for motor drives, inverters, power electronics, solar power converters, AC/DC and DC/DC converters.
