6. Kanfigareshan Halayen Fitar da Sauƙi na Wajen Layi

• PwrDownMode: Yana ba da kuzarin kashe kansa (yana buɗe da'irar) kuma yana fitar da fitarwa na yanzu zuwa 0mA. Wannan shine mafi aminci yanayin.

• HoldLastVal: Yana riƙe fitarwa a ƙimar ƙarshe da aka karɓa daga mai sarrafawa kafin sadarwa ta ɓace.

• Output_Value: Yana fitar da fitarwa zuwa ƙimar aminci da aka riga aka tsara.

• Lokacin da tsarin ya rasa sadarwa tare da mai sarrafawa, za a iya tsara halayen kowane fitarwa:

7. Zafafa-Swappable da Soft-Farawa Ƙarfin

• Yana goyan bayan shigarwa ko sauyawa ba tare da cire wuta ba (zafin-swapping), sauƙaƙe tsarin kulawa da haɓakawa.

• Samfurin ya haɗa da da'irar farawa mai laushi wanda zai iya iyakance inrush halin yanzu yayin ƙarfin wuta, yana kare wutar lantarki da kayan aiki.
