Landlord said: This is mainly about an infrared remote control circuit principle and design, part four is the focus, with the circuit diagram to illustrate the specific process-receive, count, meet the conditions trigger control circuit!From elecfans:http://www.elecfans.com/article/88/131/198/2015/20151215394306.htmlFi

, the dielectric inside the battery can withstand a large amount of charging current, so the external can charge the lithium battery by a large amount of current, in order to shorten the charging time. The charging current in this phase is generally determined by a pin external to the charging management IC and a resistor. The resistance value is calculated based on the formula on the datasheet of the Charging management IC. 3. Constant Pressure Charging phase (already filled with more than 85%

1. The type of filter circuit and the advantages and disadvantages of each type.2. Filter circuit design (take Butterworth type low pass for example).3. According to the principle of low-pass filter circuit to promote the design of high-pass, band-pass, band resistance.=====

Modern integrated op amps (op amp) and instrumentation Amplifiers (In-amp) offer a number of benefits to design engineers compared to discrete devices. Although many clever, useful and attractive circuits are provided. This is often the case because a hasty assembly of the circuit ignores some very basic problems, causing the circuit to fail to achieve its intend

This article combined with my personal experience, through a simple example, to illustrate some of the characteristics of analog circuit design, I hope to engage in analog circuit design related direction of the students have some help.Theoretical knowledgeAnalog circuit nee

PLC uses a ladder chart language that is extremely similar to the circuit diagram of the relay. If PLC is used to transform the relay control system, it is a shortcut to design a ladder chart based on the relay circuit diagram. This is because the original relay control system has been used and tested for a long time and has been proved to be able to complete the

Design of constant current source circuitRecently due to job needs and personal interests, want to learn the constant current source of circuit design, and make a reliable constant current source.Search from the Internet a bit of information, found that not too much, only a few links have reference value, here want to summarize.First select a few of the original

shock, which brings great inconvenience to the users in the process of use. In order to protect the switching power supply itself and the load, according to the principle and characteristics of DC switching power supply, the design of overheat protection, overcurrent protection, over-voltage protection and soft start protection circuit. Principle and characteristics of 2 switching power supply 2.1 Workin

working cycles, the initial values of the voltage or current of a circuit are basically equal or very close, we can think that the switching power supply has entered a stable working state.When the switching power supply enters the stable state, for simplicity, we generally use the average or half-wave average of voltage or current for circuit calculation or analysis. For example, when calculating the curr

-time performance. Therefore, the topology structure and communication protocol of the physical bus are particularly critical. 2 Interface DesignGood interface design should ensure good anti-interference, stability and scalability of the system on the hardware. This system selects a half-duplex interface chip sn65hvd3082 with high cost performance. It has the following features:① Meet or exceed the requirements of TIA/EIA-485A standards;② Low static c
