Introduction

AI Translation

Drives two N-channel MOSFETs in a high-side/low-side configuration. The UCC27284 is a high-performance N-channel MOSFET driver with a maximum switching node (HS) voltage rating of 100V. This device enables control of two N-channel MOSFETs in half-bridge or synchronous buck topologies. With 3A peak sink and source currents and low pull-up and pull-down resistances, the UCC27284 drives high-power MOSFETs with minimal switching losses during MOSFET Miller plateau transitions. Because the inputs are independent of the supply voltage, the UCC27284 is compatible with both analog and digital controllers. For applications such as secondary-side full-bridge synchronous rectification, overlap between the two inputs and their respective outputs is supported when required.

The input pins and HS pin are capable of withstanding large negative voltages, enhancing system robustness. The enable and disable functions provide additional system flexibility by reducing gate driver power consumption and responding rapidly to fault events within the system. The 5V UVLO allows the system to operate at lower bias voltages, which is required in many high-frequency applications and can improve system efficiency in certain operating modes. Small propagation delay and delay matching specifications minimize dead-time requirements, further improving efficiency.

Both the high-side and low-side driver stages feature UVLO, which forces the output low when the VDD voltage falls below the specified threshold. In many applications, the integrated bootstrap diode eliminates the need for an external discrete diode, saving board space and reducing system cost. The UCC27284 is available in a small package to support high-density designs.
