你好,我想请问一下
我在应用手册中看到了对于DESAT引脚保护二极管的一段描述
描述中提到了“不允许低于-0.3V”,但没有具体指出是哪个参数不允许低于-0.3V。我猜测是导通压降不允许低于0.3V?
请问我猜测的正确吗?谢谢!
已解决! 转到解答。
Hi,
if my translation of your question is correct, you would like to know which parameter is limited to "-0.3V", the voltage on the "DESAT"-Pin (referenced to GND2) is not allowed to be lower than "-0.3V". Please have a look on page 18 in the datasheet "Absolute maximum ratings => DESAT voltage". Hope this helps.

Hi ZhangLi1,
根据datasheet的参数表, 1ED3322MC12N 的Desat pin的最大额定值范围在-0.3V到Vcc2+0.3V之间(参考GND2),所以选择的保护二极管的正向导通压降的绝对值不应高于0.3V。
