UCC27284/UCC27284-Q1 120V Half-Bridge Gate Drivers

Texas Instruments UCC27284/UCC27284-Q1 120V Half-Bridge Gate Drivers are robust N-channel MOSFET drivers with a maximum switch node (HS) voltage rating of 100V. The devices allow for two N-channel MOSFETs to be controlled in half-bridge or synchronous buck configuration-based topologies. The drivers offer 3.5A peak sink current and 2.5A peak source current, along with low pull-up and pull-down resistance, allowing the UCC27284/UCC27284-Q1 to drive large power MOSFETs with minimum switching losses during the transition of the MOSFET Miller plateau. Since the inputs are independent of the supply voltage, UCC27284/UCC27284-Q1 can be used in conjunction with both analog and digital controllers. Two inputs, and therefore outputs, can be overlapped, if needed, in applications such as secondary side full-bridge synchronous rectification.
