LM3881EVAL 的说明
This evaluation board is designed to permit the designer to connect it directly to the Enable or Remote ON/Off pins of power supply devices of an existing system to facilitate system sequencing. Upon enabling the device, the three open drain output flags will rise in sequential order, 1-2-3. Once the part is disabled, the shutdown sequence will occur in reverse order 3-2-1. Therefore the last power supply that started up will be the first to shutdown.
