EVAL-L9177A demo board hardware
Introduction
The EVAL-L9177A is an Evaluation Board designed to evaluate L9177A, a smart power
device designed by STMicroelectronics in advanced BCD technology.
L9177 is able to drive all the relevant loads used in one/two cylinder powertrain applications
(Injectors, Relay, stepper motor, tachometer, etc.), to interface with Variable Reluctance
Sensors and Hall sensors, to monitor diagnostic functionalities and to interact with the main
networks present in powertrain environment (K-Line).
All channels are protected against short circuit and over-temperature condition.
The board can be connected to the SPC563M-DISP, the Di board developed for
the SPC563M64L.
