Zusammenfassung: | The invention provides a high-current CMOS push-pull driving circuit capable of working under a 5-10V power supply voltage and a control method of the high-current CMOS push-pull driving circuit. The high-current CMOS push-pull driving circuit is mainly applied to gate drive of a high-power MOS. The circuit comprises a DC power supply, a linear voltage stabilizing circuit (LDO), a control circuit, an NMOS, a PMOS and an output load, wherein the linear voltage stabilizing circuit and the control circuit are directly powered by the DC power supply; output of the LDO is connected with the control circuit; a PWM input signal is connected with the control circuit; and the control circuit outputs two paths of signals and is connected with gates of the NMOS and the PMOS respectively. Through self-adaptive control, opening and closing of the NOMS/PMOS are controlled according to the input PWM signal under different DC power supply voltages, so that drive on a load is achieved. The high-current CMOS push-pull driving |
