Abstract: A charging protection circuit with an overcurrent protector circuit takes input from a power supply, and provides output power to a power storage device, such as a battery. A fuse is connected between an input and an output of the charging protection circuit to protect the power storage device from a current spike, or overcurrent, that would damage the power storage device. When the overcurrent is above a threshold of the fuse, the fuse melts, effectively creating an open circuit and blocking the overcurrent from reaching the power storage device. To speed up the fuse meltdown, the overcurrent protector circuit is connected to the output of the fuse, and draws an extra current through the fuse when the overcurrent is detected.
