Beschreibung
Zusammenfassung:The invention belongs to the technical field of integrated circuits, and particularly relates to a high-voltage half-bridge driving chip and a packaging structure. The circuit is characterized by comprising a high-voltage side driving chip, a low-voltage side driving chip, an MOS tube Q1 and an MOS tube Q2, the high-voltage side driving chip and the low-voltage side driving chip are both adaptively connected with the MOS tube Q1 and the MOS tube Q2, and the low-voltage side driving chip transmits pulse control signals to the high-voltage side driving chip through the MOS tube Q1 and the MOS tube Q2. The high-voltage side driving chip and the low-voltage side driving chip are prepared by adopting a low-voltage process, substrates of the high-voltage side driving chip and the low-voltage side driving chip are P-type, and the high-voltage side driving chip and the low-voltage side driving chip are connected to the bottom metal base island through conductive adhesive. And the MOS tube Q1 and the MOS tube Q2 are p
