The UCC27289 is a robust N-channel MOSFET driver with a maximum switch node (HS) voltage rating of 100 V. It allows for two N-channel MOSFETs to be controlled in half-bridge or synchronous buck configuration based topologies. Its 3-A peak source and sink current along with low pull-up and pull-down resistance allows the UCC27289 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, UCC27289 can be used in conjunction with both analog and digital controllers. Two inputs are completely 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.
The input pins as well as the HS pin are able to tolerate significant negative voltage, which improves system robustness. Small propagation delay and delay matching specifications minimize the dead-time requirement which improves system efficiency.
Under voltage lockout (UVLO) is 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, which saves board space and reduces system cost. UCC27289 is offered in multiple packages to accommodate system requirements such as robustness in harsh environments and density in compact applications.
