Introduction

The L9805E 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, 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.
