STMicroelectronics L9026 Evaluation Board (EVAL-L9026-YO)

STMicroelectronics L9026 Evaluation Board (EVAL-L9026-YO) is a low-cost demonstration platform for the L9026 Multi-Channel Relay Driver. The L9026 is optimized for automotive LED and relay applications and is compatible with resistive, inductive, and capacitive loads. The L9026 integrates two High-Side drivers and six configurable High-Side/Low-Side drivers and can be driven by SPI or by two dedicated parallel inputs. The device offers advanced diagnostic and protection functionalities such as short to GND, open load, overcurrent, and over-temperature detections.

The EVAL-L9026-YO Evaluation Board features a pre-installed STMicroelectronics L9026 Relay Driver in an HTSSOP24 package, along with test points for key pin signals and expansion connectors. The EVAL-L9026-YO allows the complete control of the L9026 communication interface (SPI) and parallel input/output. Dip switches enable demonstration of all available configurations. The Evaluation Board can be also controlled using a Graphical User Interface.
