High-Side FET drivers provide the ability to switch Desktop, Notebook, and Netbook power rails ON and OFF in a more efficient and linear manner by facilitating the use of N-channel MOSFETs rather than typical P-channel MOSFETs. High-Side FET drivers substantially reduce part count, thereby saving sleep mode power (via reduction in leakage current) and reducing PCB area at cost parity with existing solutions.

High-Side FET drivers also provide support for any Intel Reference design load switch for ramp rate or delay. Additionally, High-Side FET drivers can help your products meet current and future EnergyStar specifications without increasing cost.
