Title:
ELECTRONIC CIRCUIT, MODULE, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/176097
Kind Code:
A1
Abstract:
This electronic circuit comprises: a load; a load switch for switching a connection state between a power source and the load to either of a conductive state or a non-conductive state; a first power conversion circuit for outputting first DC power on the basis of first power obtained by a first electric wave received by a first antenna; a second power conversion circuit for outputting second DC power on the basis of second power obtained by a second electric wave received by a second antenna; and a control circuit having a first input terminal, a second input terminal, and an output terminal which makes the load switch conductive when the first DC power is input to the first input terminal, and makes the load switch non-conductive when the second DC power is input to the second input terminal. The load switch is controlled to maintain the conductive state even if the second electric wave is received by the second antenna when the load switch is in the conductive state.
