| description | The invention relates to a battery reverses connection-prevention circuit and a charger. According to the battery reverses connection-prevention circuit and the charger, a current absorption unit, a filtering unit and a reverses connection-prevention unit are adopted. In an actual application process, when a battery is reversely connected, a control chip outputs a high-level signal to a MOS transistor Q1 and/or a MOS transistor Q2, so that the MOS transistor Q1 and/or the MOS transistor Q2 are cut off, and therefore, residual current in the reversely-connected battery can be prevented from damaging the circuit. A resistor R1 and a resistor R2 are adopted, peak current can be absorbed, excessively high current can be prevented from damaging the circuit, and therefore, the stability of the circuit is improved. A diode D1 and a diode D2 are adopted; both the diode D1 and the diode D2 can realize an anti-backflow function, and therefore, voltage counter flow can be prevented from damagingthe circuit.
