Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

All parts are 100% tested at +25°C. Electrical limits across the full temperature range are guaranteed by design and correlation.
Latch-off current does not include the current flowing into
FLAG.
TDFN packages are guaranteed by design.
The on-time is defined as the time taken for the current through the switch to go from 0mA to full load. The off-time is defined as
the time taken for the current through the switch to go from full load to 0mA.
Note 5:
Retry time is typically 15 times the blanking time.
卡巴斯基的安全研究人员称其发现了如何攻击Intel微处理器的远程攻击代码，据传，这一代码可以通过TCP/IP包和JavaScript代码到达用户系统。 目前受影响的系统包括Windows XP，Vista，Windows Server 2003，Windows Server 2008，Linux甚至是BSD和Mac。但所幸大多数错误可以由Intel和BIOS厂商联合进行修复。 卡...[详细]
