Texas Instruments UCC23513/UCC23513-Q1 Isolated Gate Driver
Texas Instruments UCC23513/UCC23513-Q1 Isolated Gate Driver is an Opto-compatible, single-channel, isolated gate driver for IGBTs, MOSFETs, and SiC MOSFETs. This device has a 4.5A source, a 5.3A sink peak output current, and a 5.7KVRMS reinforced isolation rating. The high supply voltage range of 33V allows the use of bipolar supplies for effectively driving IGBTs and SiC power FETs. UCC23513/UCC23513-Q1 can drive both low-side and high-side power FETs. Key features and characteristics bring significant performance and reliability upgrades over standard optocoupler-based gate drivers while maintaining pin-to-pin compatibility in schematic and layout design.
Performance highlights include high common-mode transient immunity (CMTI), low propagation delay, and small pulse width distortion. A tight process control results in a small part-to-part skew. The input stage is an emulated diode (ediode) which means long-term reliability and excellent aging characteristics compared to traditional LEDs. It is offered in a stretched SO6 package with > 8.5mm creepage and clearance and a mold compound from material group I with a comparative tracking index (CTI) > 600V.
The UCC23513/UCC23513-Q1’s high performance and reliability make it ideal for use in all types of motor drives, solar inverters, industrial power supplies, and appliances. The higher operating temperature opens up opportunities for applications not previously able to be supported by traditional optocouplers. The Texas Instruments UCC23513-Q1 devices are AEC-Q100 qualified for automotive applications.
