Beijing Haihua Boyuan Science and Technology Development Co. Ltd is a high-tech company which has committed to develop integration of machinery-and-electrics products as well as optimization and integration of Motion Control System for years, and firstly launched Motion Control Chips with its own property right in domestic market. Up to now, Beijing Haihua Boyuan Technology Development Co. Ltd has become a company including R&D and producing as well as sales of machinery-and-electronic products as a whole.Based on the current situation of domestic market of stepping motor drivers, we engaged in cooperation with famous international semi-conductor companies (SANYO Semiconductor Co.Ltd & TOSHIBA Semiconductor Company)and after years of trialing and improvement, the specification of the both two-phase hybrid stepping motor driver chips of THB6064H THB6128 THB7128 have reached international level. And other series products ( THB8128 THB9128 ) are also under research and development.This three chips include logical and function module which could realize high-performance, multi-microstepping and high current stepping motor drive just with a simple peripheral circuits. In addition, the chips have a character of low vibration, small noise and high-speed, and they can comprehensively cover every kind of two-phase hybrid stepping motor below 60mm motor that made them the perfect alternatives of foreign products. Because the chips' R&D comes from domestic demand, they have a more focus character with easy application and a wider range of users. They've already got well received in domestic market.Besides the series products of stepping chips, the main products of this company also include a series of stepping motor drivers from Japanese Shinano company, BY series stepping motor drivers (including multi-subdivided two-phase hybrid stepping motor drivers below 6A and three-phase hybrid stepping motor drivers below 4A), mid & high-frequency with medium-and-Low power freque
