UCC21551/UCC21551-Q1 Isolated Gate Driver

Texas Instruments UCC21551/UCC21551-Q1 Dual-Channel Isolated Gate Driver is designed with 4A peak-source and 6A peak-sink current to drive power MOSFET, SiC, and IGBT transistors. This isolated gate driver can be configured as two low-side, two high-side, or a half-bridge driver. The input side is separated from the two output drivers by a 5kV_RMS isolation barrier, with a minimum of 125V/ns Common-Mode Transient Immunity (CMTI). The UCC21551/UCC21551-Q1 isolated gate driver enables high efficiency, high power density, and robustness in a wide variety of power applications. Typical applications include isolated converters in AC-DC and DC-DC, motor drives, inverters, and Uninterruptible Power Supplies (UPS). The UCC21551-Q1 devices are AEC-Q100 qualified for automotive applications.
