Title:
POWER SUPPLY CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2024/075487
Kind Code:
A1
Abstract:
A power supply circuit (1) comprises: a first switching unit (11) that, when a power supply signal (SUP) is input to a third terminal (T3), connects a first terminal (T1) that is connected to a power source (3) and a second terminal (T2) that is connected to a load (5); a second switching unit (12) that, when a cut-off signal CUT is input to a sixth terminal (T6), cuts off a fourth terminal (T4) that is connected to the second terminal (T2) and a fifth terminal (T5) that is connected to the third terminal (T3); a third switching unit (13) that, after inputting a power supply signal (SUP) to the third terminal (T3) through a first bypass path (BP1) that bypasses the first switching unit (11), cuts off the first bypass path (BP1); and a fourth switching unit (14) that connects or cuts off a second bypass path (BP2) that bypasses the third switching unit (13). The second bypass path (BP2) is cut off while driving power is supplied from the power source (3) to the load (5).
