EVAL-L9026-YO

EVAL-L9026-YO is a low-cost tool designed to evaluate L9026, a smart power device designed by STM in advanced BCD technology. The L9026 is an 8 channels IC, with 2 fixed HS drivers and 6 configurable HS/LS drivers designed for automotive applications and compatible with resistive, inductive and capacitive loads. It 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 = 3V and very low quiescent current under RESET condition.
