モーター駆動制御システム及び電子機器
Document Type and Number:
Japanese Patent JP6402534
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a motor drive control system capable of achieving lower current consumption, and further to provide an electronic apparatus or the like.SOLUTION: A motor drive control system 100 includes: a motor driver 200 driving a motor 280; and a processing section 110 controlling the motor driver 200. The motor driver 200 includes: a bridge circuit 210 having a high-side transistor and a low-side transistor; a control section 240 performing ON/OFF control of the high-side transistor and the low-side transistor; and a detection circuit 220 detecting a current flowing through the bridge circuit 210. The detection circuit 220 stops current detection in a given period of the motor 280 on the basis of instruction information of the processing section 110.SELECTED DRAWING: Figure 3
