The UCC27282 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. It features 3.5-A peak sink and 2.5-A peak source currents along with low pull-up and pull-down resistance, enabling the drive of large power MOSFETs with minimum switching losses. The device includes integrated features like a bootstrap diode, input interlock for cross-conduction protection, and 5-V under-voltage lockout (UVLO). The input pins and HS pin can tolerate significant negative voltages, enhancing system robustness in high-noise applications.
