| description | The utility model discloses a charging protection circuit and electronic equipment, the charging protection circuit is applied to a charging loop, the charging protection circuit comprises a loop switch piece, a reference voltage module and a detection comparison module, and the loop switch piece is connected in series in the charging loop; the first end of the reference voltage module is connected to a first driving power supply, and the second end of the reference voltage module is grounded; and the detection comparison module is connected with the control end of the loop switch piece, and outputs an overcurrent control signal based on the comparison result of the reference voltage and the reference voltage so as to control the on-off of the loop switch piece. The over-current protection function in the charging and discharging process of the rechargeable battery is achieved, and damage to the rechargeable battery caused by over-current charging and discharging is avoided.
