Single-channel isolated gate driver is a good fit for motor drives and industrial power supplies

Texas Instruments’ UCC53x0 is a family of compact, single-channel, isolated IGBT, SiC, and MOSFET gate drivers with superior isolation ratings and variants for pinout configuration, and drive strength. The family is available in an eight-pin SOIC (D) package. This package has a creepage and clearance of 4mm and can support isolation voltage up to 3kVRMS, which is good for applications where basic isolation is needed. With these various options and wide power range, the family is a good fit for motor drives and industrial power supplies. The UCC53x0S option provides a split output that can be used to control the rise and fall times of the driver. The UCC53x0M option connects the gate of the transistor to an internal clamp to prevent false turnon caused by Miller current. The UCC53x0E option has its UVLO2 referenced to GND2, which facilitates bipolar supplies. Unlike an optocoupler, the family has lower part-to-part skew, lower propagation delay, higher operating temperature, and higher CMTI.
