简单输入适配器反向电压保护

标签：电源技术资料下载,
Modern electronic systems require a host of different regulated voltages to power various subsystems. The number of voltage rails has risen as new generations of processors, memory, etc. have been introduced with lower voltage requirements driven by deep sub−micron CMOS processes. One of the consequences of these new process technologies is that the absolute maximum ratings have also been lowered, therefore designers are forced to employ protection circuitry to protect sensitive I/O’s from transient and steady−state overvoltage and reverse voltage conditions.， 大小：8.12 MB
