一、电压的作用对象不同 VCC的供电电压作用于电路。VDD的工作电压作用于芯片。VSS的电压作用于器件内部。二、来源不同 VCC来源于集电极电源电压， 一般用于双极型晶体管。VDD来源于漏极电源电压，用于 MOS 晶体管电路, 一般指正电源。Vss来源于极电源电压，在 CMOS 电路中指负电源, 在单电源时指零伏或...
一、解释 (1)VCC:C=circuit...电压VCC一般为5V,一般经过稳压模块将其转换为单片机工作电压VDD=3.3V2、有些IC既有VDD引脚又有VCC引脚,说明这种器件自身带有电压转换功能。 3、在场效应管(或COMS器件 迟滞比较器 MCP6002T-I/SN ) Uix10/(10+78.7)=3.15 Ui=27.9V当Ui从36V到27.9V时,Uo从VCC到0V本电路...

Simulate the circuit:Once the VCC has been added to the circuit design, it is time to simulate the circuit and verify its behavior. The Simulations toolbar is the perfect place to start. Adding a VCC to your circuit in the Multisim environment should be straightforward and easy to understand...
Basically in any BJT, FET, etecetra containing circuits you have the following terms: Vbb, Vcc, Vee, Vb, Vc, Ve, Vbe, Vce, Vbc, where b= Base c= Collector e= Emitter These are the conventions that denote the type of voltage in any given circuit. Therefore according to these conv...
We want to implement a circuit like in the picture below, were the VCC is connected to the lower voltage (SD0, SD1) instead of the SDA voltage, in this case 1.8V and we are not sure if the Vcc must be 1.8V or 3.3V, we have some concern that Vpass is too close ...
“litepipes”, too. A light pipe is a rod made of optical acrylic or polycarbonate that transmits light from a light source, typically an LED, at the circuit board to the panel of the device. These light pipes are ideal for carrying the light in a small space, like a status indicator...
The PC audio circuit includes a digital signal processor (DSP) for processing wavetable data and generating digital audio signals for a plurality of voices. The wavetable data is stored in the host computer's system memory and transferred in portions, as needed by the DSP, to a smaller, low...
I am in this article XDP™ XDPS2222: PFC + hybrid flyback combo IC For 240 W USB PD form factor reference design, I saw the part about VCC voltage regulation circuit, and I was curious why the MOSFET here chose the structure of Depletion MOSFET instead of Enhancement MO...
The LTC1470 features built-in SafeSlot™ current limit and thermal shutdown. The output is limited to 1A during short circuit to ground but 2A of peak operating current is allowed. The LTC1471 is a dual version of the LTC1470 and is available in a 16-pin SO package. ...
