Basic, 4.5A/5.3A single-channel opto-compatible isolated gate driver

The UCC23313 is an Opto-compatible, single-channel, 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 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’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.
