| description | According to the battery reverse connection prevention circuit and the charger of the utility model, the current absorption unit, the filtering unit and the reverse connection prevention unit are arranged. In an actual application process, when a battery is reversely connected, the control chip outputs a high-level signal to the MOS transistor Q1 and/or the MOS transistor Q2, so that the MOS transistor Q1 and/or the MOS transistor Q2 are/is cut off, and residual current in the reversely connected battery is prevented from damaging a circuit; besides, a resistor R1 and a resistor R2 are arranged, so that the effect of absorbing peak current can be achieved, the circuit is prevented from being damaged by overhigh peak current, and the stability of the circuit is improved; moreover, the arrangement of the diode D1 and the diode D2 plays a role in preventing backward flowing, so that the circuit is prevented from being damaged by reverse current of voltage.
