Circuit and electronic equipment

The utility model discloses a circuit and an electronic device. The circuit includes first and second input power supply nodes that receive a power supply voltage therebetween. The circuit includes a high-side driver circuit coupled to a high-side switch and generating a first signal between first and second high-side output nodes. The circuit includes a low-side driver circuit coupled to the low-side switch and generating a second signal between the first and second low-side output nodes. The circuit includes: a floating node receiving a floating voltage applied between the floating node and a second high side output node; a bootstrap diode located between the first input power supply node and the intermediate node; and a current limiter circuit located between the intermediate node and the floating node, sensing a floating voltage, and canceling a current flowing from the intermediate node to the floating node as the floating voltage reaches a threshold. The technology of the utility model provides a driver
