PROGRAMMABLE DYNAMIC VOLTAGE CONTROL APPARATUS

摘要

The present invention relates to a programmable dynamic voltage control apparatus, and more particularly, to a programmable dynamic voltage control apparatus which is capable of dynamically controlling voltage conversion of an output unit using data set in programmable memories, when various pieces of information sensed by a variety of sensors mounted in a vehicle are converted into electrical signals and then transmitted.

1. A programmable dynamic voltage control apparatus comprising:
an n-bit channel data storage unit configured to store an n-bit digital input channel selection number and one or more programmable dynamic data for setting divided voltages corresponding to the n-bit digital input channel selection number, and provide the stored n-bit digital input channel selection number and dynamic data for setting the 2n divided voltages to a voltage division unit; the voltage division unit configured to equally divide an input voltage to generate 2N divided voltages VM(i) where i ranges from 1 to 2N and N is the number of necessary steps, select the 2n divided voltages corresponding to the n-bit digital input channel selection number from the 2N divided voltages VM(i) through the programmable dynamic data provided from the n-bit channel data storage unit, and maps the selected 2n divided voltages to 2n applied voltages V(j) of a D/A conversion unit; and the D/A conversion unit configured to be turned on/off by receiving the 2n applied voltage V(j) mapped through the programmable dynamic data and receiving a digital sensor signal sensed through a sensor of a vehicle as input signals of n channels, and output an analog signal corresponding to the digital input signal of each channel.
