Abstract
A detection circuit includes an open circuit detection branch and a current detection branch. The open circuit detection branch includes a comparator and a digital logic branch. A positive input terminal of the comparator is connected to one end of the sampling resistor adjacent to the stimulation source, a negative input terminal of the comparator is connected to one end of the sampling resistor facing away from the stimulation source, and an output terminal of the comparator is connected to the digital logic branch. The current detection branch includes an amplifier and a first switch. A negative input terminal of the amplifier is connected to the one end of the sampling resistor facing away from the stimulation source, an output terminal of the amplifier is connected to a control terminal of the first switch.
