UCC27712D

Gate Driver Overview

The UCC27712D is a high-side and low-side half-bridge gate driver designed to drive power MOSFETs or IGBTs. It features a 1.8A source current and a 2.8A sink current, operating with bias supply voltages from 10V to 22V. The device withstands up to 620V and has a maximum absolute voltage of 700V on the HB pin. Key electrical parameters include a typical propagation delay of 100ns, delay matching of 12ns, rise time of 16ns, and fall time of 10ns. It operates within a temperature range of -40°C to +125°C and utilizes an SOIC-8 package.

Gate Driver Feature Summary

• Integrated interlock and dead-time functionality prevents simultaneous output activation
• High dv/dt immunity ensures reliable operation in noisy environments
• Under-voltage lockout protection for both VDD and HB bias supplies
• TTL and CMOS compatible inputs with negative voltage tolerance

Gate Driver Applications

• Motor drives including HVAC systems and robotics
• Bridge converters in offline AC/DC power supplies
• High-density switching mode power supplies for server infrastructure
• DC-AC inverters

Gate Driver Procurement Notes

Verify the specific suffix 'D' indicates the SOIC-8 tube packaging variant rather than the tape-and-reel version. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement orders. Ensure the component meets the required thermal and electrical specifications for the intended application environment.

Gate Driver Selection Notes

Select this component when driving medium-power MOSFETs or IGBTs requiring robust high-side isolation. The integrated dead-time and interlock features simplify control logic design by preventing shoot-through conditions. Consider the 620V rating for applications exceeding standard low-voltage limits while maintaining compact footprint requirements.

Gate Driver Part Context

This part belongs to the UCC27712 family of half-bridge drivers. It shares functional similarities with the UCC27710 but offers higher peak output currents. The device is distinct from the automotive-grade UCC27712-Q1, which holds AEC-Q100 certification. It serves as a critical interface between low-voltage control circuits and high-voltage power stages.

Gate Driver Replacement Considerations

The UCC27710 is a lower-current alternative within the same family. Verify pin compatibility and current drive requirements before substituting. No direct cross-manufacturer equivalents are confirmed in the provided data.
