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

The UCC23313-Q1 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-Q1 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-Q1’s high performance and reliability

makes it ideal for use in automotive motor drives such as the traction inverter, on-board

chargers, DC charging stations, and automotive HVAC and heating systems. The higher

operating temperature opens up opportunities for applications not previously able to be

supported by traditional optocouplers.
