Texas Instruments UCC2154x/UCC2154x-Q1 Dual-Channel Gate Driver

Texas Instruments UCC2154x/UCC2154x-Q1 Dual-Channel Gate Driver is an isolated gate driver designed with up to 4A/6A peak source/sink current to drive power MOSFET, IGBT, and GaN transistors. The UCC21540 in the DWK package also offers 3.3mm minimum channel-to-channel spacing, which facilitates higher bus voltage. The UCC2154x/UCC2154x-Q1 can be 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 5.7kVRMS isolation barrier, with a minimum of 100V/ns common-mode transient immunity (CMTI).

Protection features include resistor programmable dead time, disable feature to shut down both outputs simultaneously, and an integrated de-glitch filter that rejects input transients shorter than 5ns. It also features negative voltage handling for up to –2V spikes for 200ns on input and output pins. All supplies have UVLO protection. The Texas Instruments UCC2154x-Q1 devices are AEC-Q100 qualified for automotive applications.
