| titleOfInvention | A kind of ultrasonic sensor |
| abstract | The utility model provides a kind of ultrasonic sensor, the ultrasonic sensor is the ultrasonic sensor based on TL851 chip and TL852 chip, including TL851 chip, TL852 chip, inverter, ultrasonic transducer and triode, inverter includes contravariant transformer, one end of contravariant transformer primary side is for connecting power supply, the collector of other end connecting triode, the emitter ground connection of triode；The secondary side of contravariant transformer connects ultrasonic transducer；The base stage of the signal output end connecting triode of TL851 chip；Current-limiting resistance is provided on the route of the signal output end connecting triode base stage of model ZXTN2010ZTA, the TL851 chip of triode.Technical solution provided by the utility model increases the triode power of driving inverter, reduces the driving current of triode, be able to solve ultrasonic sensor in the prior art and be easy to appear the poor problem of failure, reliability. |
