Enhanced-N Channel MOS tube (e.g. si2300) switching conditions An enhanced n-Channel MOS Tube's s (source source) and D (drain drain) conduction conditions depend on the VGS, the voltage dropout between the gate and the source. only if vgs > 2.5V, which is vg (G-pole voltage)- vs (S-pole voltage) > 2.5v,d and S-poles conduction. For example: G extremely 3.3V, s extremely 0.1V, vgs = 3.3-0.1 = 3.2V > 2.5V, so D-pole and S-pole conduction, D-Pole

MoS Tube Learning in the actual project, we basically use the enhanced MOS tube, divided into N-channel and P-Channel two kinds. We often use nmos because of its low on-resistance and easy to manufacture. As can be seen on the MOS schematic, there is a parasitic diode between the drain electrode and the source. This is called a body diode, which is important in driving inductive loads such as motors. Inc

enhanced P-Channel MOS tube (e.g. SI2333DS) switching conditions when used as a switch, the PMOs tube is controlled by the VGS voltage value to control the continuity between S (source) and D (drain drain). the minimum threshold voltage for the VGS is 0.4v, which means that the source and drain electrodes are on when the S (source) voltage-G (Gate gate) Pole > 0.4V. and VS = Vd, the S-pole voltage is eq

the security administrator does not actually solve the security issue. A new generation of firewalls should enhance the security of the release data, because the real demand for network security is to ensure security, but also to ensure the normal application. This article describes the Smart Firewall is a smarter, more intelligent firewall products, it overcomes the traditional firewall "one tube dead, on the chaos" situation, fixed the above firewa

is the Guest account used or not, is this a problem? By default, many Windows systems automatically turn off the Guest account's enabled state, and many users who value the system security will not hesitate to "hit the Killer" on the guest account and not allow it to start running, in the view of these users, as long as the guest account is opened, Then the Windows system encounter hacker attacks will be inevitable! In fact, as long as we manage the Guest account skillfully, we can enjoy the gue

In this article we use Photoshop to create a rusty metal tube effect.1. Start First create a new document with a canvas size of 450 x 450 pixels with a resolution of 72. Fill the background with a very dark color #111111. 2. Draw a rectangle Create a new layer and get a flat-width selection My selection is actually set to 22px, which adds color #5e5e5e to the selection. 3. Dodge Tools Basically, the tools you need are just dodge tools: Set

Commonly used pipes have steel pipe, steel corrugated pipe, 3 kinds of plastic pipe.The advantages of the steel pipe are easy to install, can be welded in the steel skeleton outside, may replace some of the steel section, and because of the rigidity of the steel pipe. After embedding can basically maintain its parallelism and flatness, many large-diameter cast-in-situ piles are used as pipe for sound measurement. But the price of steel pipe is more expensive:Steel corrugated pipe is a kind of go

But the drive circuit is to have a certain hardware basis (such as): such as 2 pieces of 74hc573. And I only have a few

The resistor is a resistive device with a non-linear volt-ampere characteristic, most of which is protected by voltage circuitry when the circuit is under overvoltage and absorbs excess current to protect the sensitive device. Usually called VDR. The resistor body material of the resistor is a semiconductor, so it is one of the semiconductor resistors.TVS (diodes), also called TVs Tubes , are widely used as a new type of efficient circuit protection device with fast reflection time and very high

In the beginning of no digital display, the sequence is a matrix keyboard, followed by the digital tube 0~f,6 simultaneously digitally controlled static display.Digital control and Matrix keyboardFirst of all, the selection of the digital tube is closed to let the digital tube display no matter what the number. Then select all the digital

First, the circuit compositionThe regulator circuit composed of Zener diode dz and current limiting resistor R is the simplest DC regulated power supply. Two basic relations can be obtained from the regulator circuit of the regulator tube : Ui=ur+uo Ir=idz+il Voltage Regulator Tube volt-ampere characteristics such as, in the voltage regulator circuit, as long as the regulator is always wor

the semaphore is 0, it enters the waiting queue.After exiting the critical section, use the V operation, the semaphore value plus 1, if the semaphore is also less than or equal to 0, then wake up a process in the waiting queue.II) Achieve condition synchronizationA thread A uses the P operation, a thread B uses the V operation, and the initial semaphore is set to 0. To satisfy a condition, thread A can be executed only after the execution of threads B. This can be achieved easily with semaphore

negative voltage VGS between the grid sources is applied, the two PN junctions in the junction field effect tube are in the inverse state. (b) is shown. with the negative increase of the VGS, the reverse bias voltage added to the PN junction increases, and the depletion layer widens. Because of the low doping concentration of N-channel, the depletion layer is mainly concentrated on the channel side. The depletion layer widens, making the channel narr

March 24, Nanning DMV and postal departments, drivers medical institutions first batch of cooperation to open the "Car tube Convenient service network" in the Jin Pu Road Post officially launched, the same day the city at the same time to open the convenience of a total of 21 service outlets.　　In the future, the public only need to go to the nearest "car Tube convenience Service Network" to submit business

(1) using the GPIO port directly control the digital tube using 12 IO ports. In order to reduce the occupied IO port, we used a 74hc595 to drive the digital tube.(2) The 74hc595 chip has a 8-bit shift register and a memory, three-state output function. The shift register and memory have separate clocks. The data is entered into the shift register at the rising edge of the SH_CP (shift register clock input)
