Electronic apparatus and method to control electronic apparatus

Abstract

An electronic device and method for controlling one or more internal units thereof capable of preventing a peak current from being introduced into the internal units of the electronic device when the internal units are simultaneously activated. The electronic device includes: at least one internal unit; and a signal generator for generating a driving pulse having a width gradually changing in an edge region and driving the at least one internal unit. Therefore, the peak current is prevented from being introduced into the internal cells by gradually increasing or decreasing the driving pulses for driving the internal cells as time changes, or by dividing the internal cells into block units and sequentially supplying the driving pulses to the internal cells. unit.

Description

technical field [0001] The present general inventive concept relates to an electronic device and a method for driving one or more internal units thereof, and more particularly to an electronic device capable of operating in the prevents peak currents from being introduced into the internal cells when the internal cells are activated simultaneously. Background technique [0002] Generally, electronic devices include various integrated circuits such as controllers in order to realize various functions, high-speed operation performance, and miniaturization of the devices. [0003] The integrated circuit is driven by simultaneously activating internal elements such as transistors and inverters. In embodiments where internal elements are activated simultaneously, a peak current is induced into said internal elements. [0004] Hereinafter, as an example, an electronic device such as an inkjet printer will be described in order to explain a process of introducing a peak current i...
