L9805集成電路（IC）的電機驅動器控制器規(guī)格書PDF中文資料

L9805屬于集成電路（IC）的電機驅動器控制器。由意法半導體集團制造生產(chǎn)的L9805電機驅動器，控制器產(chǎn)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(xiàn)的具體功能和特性集根據(jù)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。

INTRODUCTION

The L9805 is a Super Smart Power device suited to drive resistive and inductive loads under software control. It includes a ST7 microcontroller and some pheripherals. The microcontroller can execute the software contained in the program EPROM/ROM and drive, through dedicated registers, the power bridge.

The internal voltage regulators rated to the automotive environment, PWM modules, CAN transceiver and controller, ISO 9141 transceiver, timers, temperature sensor and the AtoD converter allow the device to realize by itself a complete application, in line with the most common mechatronic requirements.
