Typical Applications
UCC21710QDWRQ1 is suitable for 6 applications: Traction Inverters, On-Board Chargers, DC-DC Converters, Motor Drives, Solar Inverters, Industrial Power Supplies.
Traction Inverters
The UCC21710QDWRQ1 is ideal for traction inverters in electric vehicles, where it drives IGBTs and SiC MOSFETs in the power stage. Its ±10A peak current and 5.7kVrms isolation ensure reliable switching of high-voltage rails, while the fast overcurrent protection (DESAT) safeguards the inverter during short circuits. The AEC-Q100 qualification and wide temperature range (-40°C to +150°C) meet automotive reliability requirements. The high CMTI (100V/ns) prevents false triggering in the noisy environment of motor drives, ensuring stable operation.

Key Differentiators
- Automotive AEC-Q100 qualification (vs UCC21710QDWQ1)
- High CMTI of 100 V/ns (vs UCC21710QDWQ1)
- Integrated DESAT protection (vs UCC21710QDWQ1)
Design Notes
For optimal performance, place the gate driver close to the power switch to minimize gate loop inductance. Use short, wide traces for the gate drive output (OUT) and return (GND2) to reduce ringing. Ensure adequate creepage and clearance distances for the 5.7kVrms isolation rating, typically at least 8mm on the PCB. Refer to TI's layout guidelines in the datasheet for recommended spacing.
The output supply (VDD) should be decoupled with a low-ESR ceramic capacitor (e.g., 1uF) placed close to the VDD and VEE pins. The input supply (VCC) should also be decoupled with a 0.1uF capacitor. Proper decoupling prevents voltage dips during high-current switching, ensuring reliable gate drive. Use a bootstrap or isolated DC-DC converter for the output supply as needed.
Ensure the DESAT protection circuit is properly designed with an appropriate blanking time to avoid false triggering during normal switching. The shunt current sensing input (OC) should be filtered to reject noise. Also, verify that the input signal (IN) is within the specified voltage range and that the UVLO thresholds are respected to prevent improper operation.
