Overview
The UCC5881QDFCRQ1 is an isolated, configurable gate driver designed for high-power SiC MOSFETs and IGBTs in EV/HEV applications. It features real-time variable drive strength with ±15A and ±5A output currents. The device integrates a 10-bit ADC for monitoring VCC2, DESAT, and die temperature. It supports active short-circuit detection on both primary and secondary sides, offering 110ns DESAT response time and protection against overvoltage and undervoltage on internal and external supplies.
Feature Summary
- Dual-output driver with real-time variable drive strength
- Integrated 10-bit ADC for analog input monitoring
- Supports primary and secondary active short-circuit detection
- Includes advanced protection against overvoltage, undervoltage, and overheating
Applications
- EV and HEV traction inverters
- EV and HEV power modules
Procurement Notes
Verify the complete datasheet availability before procurement, as some web sources indicate incomplete documentation. Confirm the specific package marking (UCC5881Q) matches the required revision. Ensure compatibility with ASIL D functional safety requirements if applicable to the system design. Check for any specific ordering suffixes that might affect pinout or electrical characteristics.
Selection Notes
Select this component when driving high-power SiC MOSFETs or IGBTs requiring adjustable drive strength. It is suitable for systems needing integrated diagnostic capabilities via the built-in ADC. Consider its isolation voltage and thermal performance for high-density power module designs. Verify that the digital input pins for drive strength adjustment fit the control logic interface.
