What are the working conditions of the TV lifter?
Jul 25, 2018

For the normal operation of the TV lifter, it is necessary to have three conditions of power supply, reset circuit and oscillation circuit, which are indispensable.

1, power supply

The power supply of the TV lifter is supplied from the power supply. The voltage is 3-5V, which is an uncontrolled voltage, that is, it enters the energy-saving state, but it should be noted that the power supply voltage cannot be lost. Otherwise, the TV lifter cannot be recovered.

2, reset circuit

Its function is that the TV lifter can get the power supply moment and start working. If some parts of the TV lifter have not been reset and start working, it will lead to the program being disordered and unable to work normally. This is the TV lifter needs the reset circuit. The reason is.

3, the oscillation circuit

All the work of the TV lifter is done under the action of the clock pulse, otherwise it will not work properly. The oscillating circuit is composed of an external crystal, a capacitor and an internal circuit.
