UCC23313BQDWYRQ1

The UCC23313BQDWYRQ1 isolated gate driver is a robust and reliable solution designed for automotive applications. With AEC-Q100 qualification, it meets stringent industry standards for reliability and performance in extreme conditions. Featuring a 3.75-kVRMS single-channel isolation barrier, it offers compatibility with opto-isolated gate drivers, allowing for easy drop-in upgrades. The device provides a high peak output current of 4.5 A source and 5.3 A sink, ensuring efficient power device switching. Versatility is enhanced with a maximum 33-V output driver supply voltage and 8-V (B) or 12-V VCC UVLO options. Swift and precise operation is achieved with rail-to-rail output, 105-ns (maximum) propagation delay, and excellent part-to-part delay matching. The gate driver's common-mode transient immunity of 150 kV/μs, isolation barrier life exceeding 50 years, and 13-V reverse polarity voltage handling capability further contribute to its longevity and safety. The stretched SO-6 package with over 8.5 mm of creepage and clearance, along with an operating junction temperature range of -40°C to +150°C, makes it suitable for diverse automotive applications. In summary, the UCC23313BQDWYRQ1 offers a comprehensive solution, combining advanced features and robust design for reliable performance in automotive systems.

The UCC23313-Q1 is an Opto-compatible, singlechannel, isolated gate driver for IGBTs, MOSFETs and SiC MOSFETs, with 4.5-A source and 5.3-A sink peak output current and 3.75-kVRMS basic isolation rating. The high supply voltage range of 33 V allows the use of bipolar supplies to effectively drive IGBTs and SiC power FETs. UCC23313-Q1 can drive both low side and high side power FETs. Key features and characteristics bring significant performance and reliability upgrades over standard opto-coupler based gate drivers while maintaining pin-to-pin compatibility in both schematic and layout design. Performance highlights include high common mode transient immunity (CMTI), low propagation delay, and small pulse width distortion. Tight process control results in small part-to-part skew.

The input stage is an emulated diode (e-diode) which means long term reliability and excellent aging characteristics compared to traditional LEDs found in optocoupler gate drivers. It is offered in a stretched SO6 package with > 8.5-mm creepage and clearance, and a mold compound from material group I, which has a comparative tracking index (CTI) > 600 V. UCC23313- Q1's high performance and reliability makes it ideal for use in automotive motor drives such as the traction inverter, on-board chargers, DC charging stations, and automotive HVAC and heating systems. The higher operating temperature opens up opportunities for applications not previously able to be supported by traditional optocouplers
