Texas Instruments UCC27289 120V Half-Bridge Drivers

The TI UCC27289 Drivers feature a 3.5A peak sink current, 2.5A peak source current, and 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 with 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 driver power consumption and responding to fault events within the system.

Protection features include under-voltage lockout (UVLO) for both the high-side and low-side driver stages, forcing the outputs to be 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.
