LB11696V集成電路（IC）的電機驅動器控制器規(guī)格書PDF中文資料

LB11696V屬于集成電路（IC）的電機驅動器控制器。由安森美半導體公司制造生產的LB11696V電機驅動器，控制器產品屬于電機驅動器和控制器電源管理集成電路 (PMIC) 系列，可用于控制或操作從某電源施加到電機或相關機電執(zhí)行器的電源。所實現的具體功能和特性集根據預期負載和預期應用的特性有很大差異，范圍從用于有刷電機的簡單開環(huán)速度控制到基于步進電機的高級閉環(huán)運動控制。

Overview

The LB11696V is a direct PWM drive predriver IC designed for three phase power brushless motors. A motor driver circuit with the desired output power (voltage and current) can be implemented by adding discrete transistors in the output circuits. Furthermore, the LB11696V provides a full complement of protection circuits allowing it to easily implement high-reliability drive circuits. This device is optimal for driving all types of large-scale motors such as those used in air conditioners and on-demand water heaters.
