"-15V EN" connects to the MUC interface to enable or disable it。
How to design the circuit of the control part of the EN so that it meets the pin power range requirements of the EN in the IC manual, and at the same time meets the interface voltage of the MCU also meets the safety requirements, and can normally control the on-off -15V power output？
It is not possible to know that this EN pin inside the IC opens the condition when the negative pressure is 15V design, how to understand？
但使用负压输出的设计时候，GND引脚接到输出-15V，在此条件时如何理解EN的电源范围？
