STEVAL-L9026

STEVAL-L9026 Evaluation Board

STMicroelectronics STEVAL-L9026 Evaluation Board is designed to evaluate the L9026 smart power device created with advanced BCD technology. The L9026 is an 8-channel IC with two fixed HS drivers and six configurable HS/LS drivers designed for automotive applications (LEDs and relays) and compatible with resistive, inductive, and capacitive loads. The IC offers advanced diagnostic and protection functionalities such as short-to-GND, open load, overcurrent, and overtemperature detection. Thanks to a programmable internal multiplexer, the eight output channels can be driven by SPI or by two dedicated parallel inputs associated with different outputs. Limp home functionality is also featured, allowing two selected drivers in specific fault conditions, such as SPI fault, microcontroller fault, or supply UV. Daisy chain compatibility with 8-bit SPI is also available. The device ensures operation in cranking scenarios down to V_BATT = 3V and very low quiescent current in the SLEEP condition.
