Abstract
The present invention discloses a totem-pole circuit. The totem-pole circuit comprises a triode Q1, a triode Q2, a diode D1 and a diode D2, wherein the triode Q1 and the diode Q2 are of an NPN type. The collector electrode of the triode Q1 is connected with an input voltage Vin, the input voltage Vin is connected with the base electrode of the triode Q1 through a resistor R1, the base electrode ofthe triode Q1 is connected with the collector electrode of the triode Q2 through a diode D2, and the emitter electrode of the triode Q1 is connected with the collector electrode of the triode Q2 through a diode D1. The base electrode of the triode Q2 inputs a driving pulse signal PWM, the emitter electrode is grounded, and the collector electrode is connected with the driving output end. The circuit provided by the invention has more stable circuit performance in a high-temperature environment, and also has a reverse output function.
