3 Description

The UCC23525 drivers are opto-compatible, singlechannel,

isolated gate drivers for IGBTs, MOSFETs

and SiC MOSFETs, with 5A source and 5A sink

peak output current and 5kVRMS reinforced 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.
