Below is the circuit diagram of the Nokia mobile travel charger circuit diagram
Nokia mobile travel charger circuit diagram
The random travel charger for the Nokia 8210 mobile phone produced in Shanghai is marked with the input AC220V/50Hz (<=30mA) and the output 4.2V (<=200mA). In charging, the nominal 3.6V The lithium battery to be charged, when charged to 3.98V, the red light of the charger circuit is off and the green light is on. The entire charging time is about four hours. The author has analyzed the charger and drawn the circuit diagram for reference by the reader for use and maintenance. The op amp ICs in the circuit are used as comparators.
Displacement sensor, also known as linear sensor, is a linear device belonging to metal induction. The function of the sensor is to convert various measured physical quantities into electricity. In the production process, the measurement of displacement is generally divided into measuring the physical size and mechanical displacement. According to the different forms of the measured variable, the displacement sensor can be divided into two types: analog and digital. The analog type can be divided into two types: physical property type and structural type. Commonly used displacement sensors are mostly analog structures, including potentiometer-type displacement sensors, inductive displacement sensors, self-aligning machines, capacitive displacement sensors, eddy current displacement sensors, Hall-type displacement sensors, etc. An important advantage of the digital displacement sensor is that it is convenient to send the signal directly into the computer system. This kind of sensor is developing rapidly, and its application is increasingly widespread.
