UCC21222/UCC21222-Q1 Dual-Channel Gate Drivers

Texas Instruments UCC21222/UCC21222-Q1 Isolated Dual-Channel Gate Drivers with programmable dead time provide a 4A Peak Source and 6A Peak Sink Output capable of driving power MOSFET, IGBT, and GaN transistors. Flexible configuration options include two low-side drivers, two high-side drivers, or a half-bridge driver. Two outputs can be paralleled due to 5ns delay matching performance, resulting in the drive strength doubling for heavy load conditions without the risk of internal shoot-through. A minimum of 100V/ns common-mode transient immunity (CMTI) enables the input side to isolate from the two output drivers by a 3.0kVRMS isolation barrier. The programmable dead time adjusts for system constraints, preventing output overlap and improving efficiency. UVLO protection is available on all supplies. The Texas Instruments UCC21222-Q1 devices are AEC-Q100 qualified for automotive applications.
