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.

Power Up and Power Down Procedure

5 Power Up and Power Down Procedure

5.1 Power Up (CL= 1000 pF)

1. Before proceeding to the power up procedure, make sure that Section 4.3.6 is implemented for setting up all the equipment. Figure 3 can be used as reference.

2. Enable supply #1.

3. Enable supply #2.The quiescent current on DMM1 and DMM2 ranges in 1 mA to 3 mA if everything is set correctly.

4. Enable function generator output.

5. Afterward, the following occurs:

1. Stable pulse output on the channel-A and channel-B in the oscilloscope. See Figure 3.

2. Scope frequency measurement is the same as function generator output.

3. DMM #1 and #2 should read measurement results around 5 mA–10 mA under no load conditions. For more information about operating current, refer to UCC23513 datasheet.

Test Waveforms with Different Input/Output Configurations

6 Test Waveforms with Different Input/Output Configurations

6.1 Input Side Reverse Bias

The default configuration grounds input to cathode buffer. Cathode buffer can alternatively be driven with a function generator to reverse bias input diode on turn-off. With J2 jumper (shunt) removed, cathode and anode buffers are driven 180º out-of-phase, which showcases the reverse blocking capability of the UCC23513.

6.2 Output Split Supply

The output can be configured to provide split supply operation through two unique methods. Single supply: Remove R9 and install C6 = C7 = 1 µF, R7 = 7.5 k, D2 = 5.1 V Zener, and R8 jumper. Dual supply: Remove R9 and install C11 = 0.1 µF, C12 = 2.2 µF, apply V+ from VCC to VSS, and V- from

VSS to Phase. These configurations allow output operation from -5 V off, to VCC-5V on which is commonly found in SiC

power stage configurations. Figure 5 shows operation with the latter method.

6.3 Peak Output Current Measurement Using 180nF Load

The output can be configured to measure peak output current by moving the jumper from J6 to J7. This jumpers are in a 180 nF load capacitor, C15, which can be used to indirectly measure the output current as seen in the Understanding Peak Source and Sink Current Parameters Application Note (SLLA387). Input PWM is set to 200 Hz to avoid excessive power dissipation in the driver.
