Texas Instruments UCC27289 120V Half-Bridge Drivers are robust N-channel MOSFET drivers with a maximum switch node (HS) voltage rating of 100V. The UCC27289 Half-Bridge Drivers allow two N-channel MOSFETs to be controlled in half-bridge or synchronous buck configuration based topologies.
The TI UCC27289 Drivers feature a 3.5A peak sink current and 2.5A peak source current along with low pull-up and pull-down resistance. These features support driving large power MOSFETs with minimum switching losses during the MOSFET Miller plateau transition. The UCC27289 can be used in conjunction with both analog and digital controllers since the inputs are independent of the supply voltage. Two inputs are entirely independent of each other, and thus, two outputs can be overlapped by overlapping inputs, if needed. The enable and disable functionality provides additional system flexibility by reducing power consumption by the driver and responds to fault events within the system.
Protection features include under-voltage lockout (UVLO) provided for both the high-side and low-side driver stages forcing the outputs low if the VDD voltage is below the specified threshold. An integrated bootstrap diode eliminates the need for an external discrete diode in many applications, saving board space and reducing system cost. UCC27289 is available in multiple packages to accommodate system requirements such as robustness in harsh environments and density in compact applications.
