STMicroelectronics, Inc. Power, Motor & Robotics Development Tools EVAL-L9026-YO

The EVAL-L9026-YO is an evaluation board designed for the L9026 multi-channel relay driver IC from STMicroelectronics. It operates with an input voltage range of 3 V to 18 V and features two fixed high-side drivers and six configurable high-side/low-side drivers, each capable of driving loads up to 1 A. The board supports various load types, including resistive, inductive, and capacitive loads, making it suitable for automotive applications such as LEDs and relays. The evaluation board includes a Serial Peripheral Interface (SPI) for control and diagnostics, as well as two parallel input pins that allow for flexible input mapping. It also features a configurable dip switch for setting up different configurations of the L9026. The board is designed with a 4-layer PCB measuring 80 x 65 mm and includes idle mode functionality to reduce current consumption. Additionally, it supports daisy chain configurations and provides advanced diagnostic features, including short to ground and overcurrent detection. The EVAL-L9026-YO is a practical tool for engineers looking to evaluate and implement the L9026 driver in their projects.
