Using the UCC23513-1EVM-014
The UCC23513-1EVM-014 evaluation module is designed for evaluation of TI's 5-kV channel gate drivers with opto-compatible input, and UCC23511. The input is current driven, requiring between 7 mA and 16 mA for device turn-on, and can be reverse biased for turnoff. The UCC23513 is a 4-A source and 5-A peak sink current driver while the UCC23511 is capable of 1.5-A source and 2-A sink peak output current for driving Si MOSFETs, IGBTs, and SiC transistors. This user's guide covers the UCC23513-1EVM-014, which is used for evaluation of the UCC23513 and UCC23511, which are pin-to­pin compatible devices.
Developed for high voltage applications where isolation and reliability are required, the UCC2351x family of devices deliver reinforced isolation of 5 kV common mode transient immunity (CMTI) greater than 150 V/ns. It offers lower propagation delay, lower­part to-part delay skew, higher CMTI, smaller Pulse Width Distortion, and higher operating temperature, which provides significant performance upgrade over opto isolated gate drivers, while still maintaining pin­to-pin compatibility.
The input current and voltage characteristics of the e-diode™ functionally mimics the primary side of an opto-isolator. The output side VCC has a wide recommended operating range from 14-V to 33-V and allows the device to be used in a low-side or high-side configuration along with bipolar supplies for SiC Power FETs. The pin-to-pin compatibility enables designers to use the UCC23513 and UCC23511 in existing designs and new designs for motor drives, industrial power supplies, solar inverters, and UPS.

2 Description

The UCC23513-1EVM-014 evaluation board utilizes a SN74LVC2G17DBVR (dual Schmitt-Trigger buffer) to drive signal current on the primary side of the device. The board is populated with clips and 2-position headers for flexibility in connecting power and signal inputs, along with signal test points and large GND vias to enable installation of ground springs. The PCB layout is optimized with minimal loop area in the input and output paths and showcases design for high voltage between the primary side and secondary side with >8 mm creepage. For detailed device information, refer to the UCC23513 and UCC23511 datasheets and TI's Isolated gate driver solutions.
