Title:
ハイサイドスイッチ
Document Type and Number:
Japanese Patent JP7319834
Kind Code:
B2
Abstract:
To provide a high-side switch capable of preventing breakdown when a reverse bias voltage is applied between a power terminal and a ground terminal.SOLUTION: A high-side switch includes: a power terminal to which a power supply voltage is applied; an output terminal to which a load is externally connected; a ground terminal to which a ground voltage is applied; and an output transistor provided between the power terminal and the output terminal and including a body diode. The high-side switch further provided includes: a charging unit configured to charge a control end of the output transistor when the power supply voltage is lower than the ground voltage; and an interrupting unit configured to interrupt a current path from the ground terminal to the power terminal when the power supply voltage is lower than the ground voltage.SELECTED DRAWING: Figure 1
