L9805E中文资料超智能电源电机驱动器，具有8位MCU、RAM、EEPROM、ADC、WDG、定时器、PWM和H桥驱动器数据手册ST规格书

描述 Description

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.
