UCC57102ZQDRQ1

Overview

The UCC57102ZQDRQ1 is an automotive-grade, single-channel low-side gate driver designed for high-performance IGBT and SiC applications. It features a typical peak drive strength of 3A and includes comprehensive protection mechanisms such as desaturation (DESAT) detection with programmable delay, under-voltage lockout (UVLO), fault reporting, and thermal shutdown. The device operates within a bias voltage range of 8.5V to 26V and supports input voltages down to -5V to accommodate ground bounce. Packaged in an SOIC-8 format, it meets AEC-Q100 standards for automotive reliability.

Feature Summary

• Integrated DESAT protection with programmable delay for advanced fault management
• Robust input stage capable of handling -5V signals to mitigate ground bounce effects
• Automotive qualification compliant with AEC-Q100 standards for harsh environments
• Self-protective design featuring thermal shutdown and under-voltage lockout

Applications

• HEV/EV PTC heaters
• Traction inverters
• Active discharge circuits
• Motor drivers

Procurement Notes
