TI UCC5350SBQDRQ1

The UCC5350-Q1 is a single-channel, isolated gate driver with 5-A source and 5-A sink minimum peak current designed to drive MOSFETs, IGBTs, and SiC MOSFETs. The UCC5350-Q1 has the option for Miller clamp or Split Outputs. The CLAMP pin is used to connect the transistor gate to an internal FET besides the output to prevent false turn-on caused by Miller current. The split outputs option allows separate control of the rise and fall times of the gate voltage with OUTH and OUTL pins. The UCC5350-Q1 is available in a 4 mm SOIC-8 (D) or 8.5 mm wide body SOIC-8 (DWV) package and can support isolation voltage up to 3-kVRMS and 5-kVRMS, respectively. The input side is isolated from the output side with SiO2 capacitive isolation technology with longer than 40 years isolation barrier lifetime. The UCC5350-Q1 is a good fit for driving IGBTs or MOSFETs in applications such as high-voltage traction inverters and on-board chargers. Compared to an optocoupler, the UCC5350-Q1 device has lower part-to-part skew, lower propagation delay, higher operating temperature, and higher CMTI.
