The following mainly through the use of NPN transistor switching circuit design, PNP transistor switching circuit similar to NPN.First, the transistor switch circuit design feasibility and necessity Feasibility: The person who used the transistor is clear, transistor has a characteristic, is saturated and cut off state, precisely because of these two states, so that it can be applied to the switching circuit is possible. Necessity: Suppose we in the design of a system circuit, some voltage, sign

Beaglebone Black Tutorial Beaglebone black device Connection Beaglebone Black The material to be prepared before developmentAfter the above introduction, I believe you have a general understanding of beaglebone, you need to notice that the completion of one thing may have many different ways. Therefore, depending on the project you want to complete, the material will be different, the following materials can help you complete the book most of the project, but not necessary: Q Beaglebone

We often see 0 euro resistance in the circuit. For new users, it is often confusing: since it is a 0 euro resistance, it is a wire, why should we install it? Is there such a resistance market available? In fact, 0 euro resistance is quite useful. The following functions are available:① Used as jumper. This is both beautiful and easy to install.② In digital and analog hybrid circuits, it is often necessary to separate the two and single point connection. We can use a 0-euro

1. What is OC and OD? Open collector gate (open collector oC or open source OD)Open-drain refers to the open-collector output, that is, the open-collector output in TTL.It is generally used for wire or, wire and some are also used for current driving.Open-drain is for MOS tubes, and open-collector is for bipolar tubes, there is no difference in usage.Open-drain circuit has the following features:1. Use the drive capability of the external circuit to reduce the internal drive of the IC.Or drive l

, CML, Hstl, Sstl and so on. The following is a brief introduction to the respective power supply, level standards and precautions to use. The Ttl:transistor-transistor logic transistor structure. vcc:5v;voh>=2.4v;vol because there is a great deal of idle between 2.4V and 5V, there is little benefit in improving the noise tolerance, and it will increase the power consumption of the system and also affect the speed. So I cut off a part of it later. That's the back of the Lvttl. The Lvttl is a

LDO current regulator for power LEDChallengeYou ' ve got a power LED? great! Build a flash light!What does the spec say? "voltage:3.6. 3.8 V, Power 3 W. " Okay. This means it draws some. Three Mignon cells give 4.5 V for at least three hours. So we add a resistor of 1.2 ohms and we are safe. If the LED runs at 3.6 v this gives MA and 2.8 W while the resistor voltage are 0.9 v resulting in 0.675 W for the Re

Olympian Sincerity The relationship between resistance value and temperature variation is: RT = RN EXPB (1/t–1/tn) RT: NTC thermistor resistance at te

resistors , low output only Level . If you want to have a high-level output function at the same time, you need to connect the resistor, A good advantage is that changes the voltage of the pull-up power supply. You can change the transmission level. for example, with the pull-up resistor, TTL/CMOS level output. ( the resistance of the pull-up resis
