Digital tube driving chip and household appliance using chip

Abstract

The invention is applicable to the technical field of electronic circuits and provides a digital tube driving chip. The digital tube driving chip is integrated with a crystal oscillation / frequency division module, a communication / control module, a display / key scanning module, a real-time clock module, a remote-control receiving module and a power management module. When a system is in a standby state, a main control chip can be completely closed, the driving chip can realize the functions of real-time time display, key startup and shutdown, infrared remote-control startup and shutdown, timed startup and shutdown, and the like independently, so that low-power consumption standby is realized, and the aims of low carbon and environment friendliness are fulfilled.

Description

technical field [0001] The invention belongs to the field of electronic circuits, in particular to a digital tube drive chip and a household appliance using the chip. Background technique [0002] Home appliances such as DVD players and set-top boxes currently on the market generally have functions such as digital display, key switch, infrared remote control switch, and timer switch. Among them, the function of digital display is mainly completed by the traditional digital tube driver chip, while functions such as key switch, infrared remote control switch, timer switch are completed by the main control chip or single-chip microcomputer. [0003] The main function of the traditional digital tube driver chip is digital display and button scanning, which meets certain needs of users, but its function is single, and it relies too much on external control chips such as the main control chip or single-chip microcomputer. When the system is in standby, the main control chip or sin...

Problems solved by technology

[0003] The traditional nixie tube drive chip, the main function is digital display and button scanning, which meets certain needs of users, but its function is single, and it relies too much on external control chips such as the main control chip or single-chip microcomputer. When the system is in standby, the main control chip or single-chip microcomputer It still needs to be kept in the working state, and the system consumes a lot of standby power, which makes it difficult to meet the current energy-saving indicators

In addition, the infrared remote control switch command of home appliances is fixed at present, and the conflict with the remote control buttons of other home appliances or equipment has also caused great trouble to users.
