3 Description

The UCC23525 driversare opto-compatible, single-channel, isolated gate drivers for IGBTs, MOSFETs and SiC MOSFETs, with 5A source and 5A sink peak output current and 5kVRMSreinforced isolation rating. The high supply voltage range of 30V allows the use of bipolar supplies to effectively drive IGBTs and SiC power FETs. The UCC23525 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. The UCC23525 is offered in a stretched SO-6 package, supporting 5KVRMS reinforced isolation rating. The stretched SO-6 package has >8.5mm creepage and clearance, and a mold compound from material group I which has a comparative tracking index (CTI) >600V.

The UCC23525's high performance and reliability makes 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.
