UCC21550/UCC21550-Q1 Dual-Channel Gate Drivers

Texas Instruments UCC21550/UCC21550-Q1 Dual-Channel Gate Drivers are isolated drivers with programmable dead time and a wide temperature range of -40°C to 150°C. These gate drivers are designed with a 4A peak source and 6A peak-sink current to drive power MOSFET, SiC, GaN, and IGBT transistors. The UCC21550/UCC21550-Q1 drivers are optically isolated gate drivers configured as two low-side drivers, two high-side drivers, or a half-bridge driver. The input side is isolated from the two output drivers by a 5kV_RMS isolation barrier, with a minimum of 125V/ns Common-Mode Transient Immunity (CMTI). These gate drivers are ideal for on-board battery chargers, high-voltage DC-DC converters, automotive HVAC, and body electronics.
