Abstract

The invention provides a drive circuit of an electron device. The drive circuit comprises a voltage conversion and stabilization unit, a waveform generation unit and a driving unit, wherein the inputend of the voltage conversion and stabilization unit is used for receiving an input power supply; the input end of the waveform generation unit is coupled with the output end of the voltage conversionand stabilization unit, and the output end of the waveform generation unit provides signals with the waveform changing periodically; the signal input end of the driving unit is coupled with the output end of the waveform generation unit, the power input end of the driving unit is used for receiving the input power supply, and the output end of the driving unit is used for providing a drive powersupply for the electron device. The drive circuit has the advantages that the work voltage range is wide, and the requirements for the work voltage range from 1.8V to 36V can be met at the same time;there are no extra components on the periphery, the drive circuit is simple and easy to produce and debug, and the cost is saved; meanwhile, the drive circuit has a certain function of resisting powerand ground reversal connection, and when 18V or below power and a ground wire are reversely connected, no damage to the circuit can be caused.

Description

technical field [0001] The invention relates to the field of electronic driving chips, in particular to a driving circuit of an electronic device. Background technique [0002] The existing buzzer driving circuit is often driven by discrete components, which has the disadvantages of large circuit size and inconvenient production and debugging. In addition, there is also the shortcoming that the working voltage range is too narrow, which is generally limited to below 5V. Contents of the invention [0003] Aiming at one or more problems in the prior art, the object of the present invention is to provide a driving circuit for an electronic device (such as a buzzer) that has a wide operating voltage range, does not require external components, or operates stably and reliably. [0004] In order to solve the above problems, one aspect of the present invention proposes: [0005] A drive circuit for an electronic device, including a voltage conversion and stabilization unit, a w...
