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

The UCC23113

opto-compatible, single-channel, isolated gate driver for IGBTs, MOSFETs and SiC MOSFETs,

with 5-A source and 5-A sink peak output current and 1.5-kV DC functional

isolation. The high supply voltage range of 30 V allows the use of bipolar supplies to

effectively drive IGBTs and SiC power FETs. The UCC23113 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.

The high performance and reliability of the

UCC23113 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.
