Product overview
Description
The EVAL-L9026-YO is a low-cost tool designed to evaluate L9026, a smart power device designed by STMicroelectronics in advanced BCD technology. The L9026 is an eight channels 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, over-temperature detections. The 8 output channels can be either 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 using 2 selected drivers in particular, faulty, conditions, such as SPI fault, microcontroller fault or supply UV. Daisy chain compatibility even with 8bit SPI is available. The device is able to guarantee operations under cranking scenario down to VBATT = 3 V and guarantees very low quiescent current under RESET condition. A serial peripheral interface (SPI) is used for control and configuration of the loads as well as of the device; besides, status feedback of all diagnostic functions is provided. For direct control and PWM there are two input pins available: these are connected to two defined outputs by default, but additional or different output mapping can be controlled by SPI. Thanks to the expansion connectors, EVAL-L9026-YO allows the complete control of L9026 communication interface (SPI) and parallel input/output. All the possible configuration on the single channel can be easily managed thanks to dip switches. The evaluation board can be also controlled with Graphical User Interface available on PTSCONNECTUM hardware interface.
