A power control circuit for a vehicle includes a power switch, N-type semiconductor switches electrically connected between a power supply terminal to which an input voltage is applied and the power switch and in which the N-type semiconductor switches are connected back-to-back, a charge pump circuit for generating a drive voltage to drive the N-type semiconductor switches by boosting the input voltage, a reverse voltage protection circuit electrically connected between an output terminal of the charge pump circuit and a node in which the N-type semiconductor switches are connected to each other, a microcontroller for generating a pulse width modulation signal for the operation of the charge pump circuit, and a voltage attenuation circuit for attenuating the drive voltage and applying the attenuated drive voltage to the microcontroller.

Power control circuit for vehicle and operating method thereof

The present invention relates to a method for preparing N-[[1-{3-(1,2,3-triazol-1-yl)propyl}piperidin-4-yl]methyl]-4-amino-5-chloro-2-methoxybenzamide, which is a novel benzamide derivative as a 5-HT4 receptor agonist, or a pharmaceutically acceptable salt thereof; to a novel intermediate capable of being used in the preparation of the compounds; and to a method for preparing the same. The preparation methods of the present invention can be useful for mass production since a low-priced reagent and intermediate are used and the number of reaction processes is decreased, thereby saving preparation costs and improving the yield.
