Overview
The UCC21330BQDRQ1 is an automotive-grade, isolated dual-channel gate driver from Texas Instruments. It features a 3kVRMS isolation barrier and delivers a 4A peak source current and 6A peak sink current. The device supports low-side, high-side, or half-bridge configurations with programmable dead time. It operates within a junction temperature range of -40°C to +150°C and includes UVLO protection for all supplies.
Feature Summary
- Provides galvanic isolation between input and output channels via a robust dielectric barrier.
- Features programmable dead-time control to prevent shoot-through in power stages.
- Integrates surge elimination filters to suppress short-duration input transients.
- Includes disable functionality capable of simultaneously turning off both outputs.
Applications
- On-board battery chargers
- High-voltage DC-DC converters
