Abstract:
A control device for current switching includes: a universal serial bus on-the-go (USB OTG) interface for connecting to a first device; a universal serial bus (USB) interface for connecting to a second device; a booster current-limiting circuit connected between the USB OTG interface and the USB interface, where the booster current-limiting circuit, the USB OTG interface, and the USB interface form a line for the device to supply power to a device; and a measuring and controlling unit connected to the booster current-limiting circuit, where the measuring and controlling unit is configured to change, after a current switching request is received, a resistance value of a current-limiting circuit in the booster current-limiting circuit, so that the first device supplies a corresponding current to the second device. The control device for current switching and the electronic device can improve universality of the control device for current switching.
