製品概要
概要
The STEVAL-L9026 is a tool designed to evaluate the L9026 smart power device, designed by STMicroelectronics in advanced BCD technology. The L9026 is an 8-channel IC with 2 fixed HS drivers and 6 configurable HS/LS drivers designed for automotive applications (LEDs and relays) and compatible with resistive, inductive, and capacitive loads. The device offers advanced diagnostic and protection functionalities such as short to GND, open load, overcurrent, and overtemperature detection. The 8 output channels can be driven by SPI or by 2 dedicated parallel inputs that can be associated to different output thanks to a programmable internal multiplexer. Limp home functionality is also featured, which allows the use of 2 selected drivers in specific fault conditions, such as SPI fault, microcontroller fault, or supply UV. Daisy chain compatibility even with 8-bit SPI is available. The device is able to ensure operation in cranking scenarios down to VBATT = 3 V and very low quiescent current in the SLEEP condition.
A serial peripheral interface (SPI) is used for control and configuration of the loads as well as of the device. Status feedback of all diagnostic functions is also provided.
Thanks to the expansion connectors, the STEVAL-L9026 allows the complete control of L9026 communication interface (SPI) and parallel input/output.
The evaluation platform may be completed with an MCU board (AEK-MCU-C1MLIT1), which can be plugged on the STEVAL-L9026 and configured using its dedicated graphical user interface (GUI).
