Answers:    Transducer driver

Processor that drives an output contained by an electronic system. It has a current gain, which manner that a low input current from a sensor or switch is amplified in instruct to operate or drive an output transducer that needs a high current.


A transistor is a transducer driver. They have three ¡®legs¡¯ ¨C a dais, a collector, and an emitter. To activate a transistor a low current is sent to the plinth leg. A protective resistor is always attached to the bottom to keep the stand current low and to protect the transistor from damage. Once sent, the bottom current allows the transistor to saturate beside ¡®electrons¡¯, which allows the semiconductor material inside to conduct electricity. The output is usually placed between the positive supply and the collector leg of the transistor. The current flows to collector and out to the unenthusiastic supply via the emitter leg.


There are two basic types of transistor: an npn transistor and a pnp transistor. The example above is of an npn. A pnp transistor works the other track around, with its collector current attached to the denial supply and the emitter attached to the positive supply.


A transducer driver not only amplifies an electrical signal but also act as an electronic switch. For this reason transistors and other transducer drivers are one of the unsophisticated components of integrated circuits.

Shower pumps have a pressure sensor so that they turn on when at hand is a flow of water and turn rotten when the flow stops.

I guess this is what you mean.
