TEXAS INSTRUMENTS LM3881EVAL 评估板, 电源定序器
The is a LM3881 power sequencer evaluation board, 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.
