The UCC2154x is an isolated dual channel gate driver family designed with up to 4 A/6 A peak source/sink current to drive power MOSFET, IGBT, and GaN transistors. UCC2154x in DWK package also offers 3.3-mm minimum channel-to-channel spacing, which facilitates higher bus voltage.

The UCC2154x family 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 5.7-kVRMS isolation barrier, with a minimum of 125-V/ns common-mode transient immunity (CMTI).

Protection features include: resistor programmable dead time, disable feature to shut down both outputs simultaneously, and negative voltage handling for up to –5-V spikes for 50 ns on input pins. All supplies have UVLO protection.
