Title:
POWER FEEDING CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/187116
Kind Code:
A1
Abstract:
In a power feeding control device (10), N-channel type first FET (20a) and second FET (20b) are disposed in a current path through which current flows from a positive electrode terminal (Tp) to a negative electrode terminal (Tn). The drain of the first FET (20a) is disposed on the downstream side of the source. The drain of the second FET (20b) is disposed on the upstream side of the source. The cathode of a first diode (26) is connected to the negative electrode terminal (Tn). A first drive circuit (21a) and a second drive circuit (21b) switch the first FET (20a) and the second FET (20b) to ON or OFF by adjusting the gates of the first FET (20a) and the second FET (20b) having a reference potential that is the potential of the cathode of the first diode (26).
