L9026-YO-TR Configurable multi channel relay driver 2HS + 6HS/LS

The L9026 is an eight-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 device offers advanced diagnostic and protection functionalities such as: short to GND, open load, overcurrent, overtemperature detections. The eight output channels can be either driven by SPI or by two dedicated parallel inputs. Limp home functionality is also featured, which allows using two selected drivers in particularly faulty conditions, such as SPI fault, micro fault or supply UV. Daisy chain compatible even with 8bit SPI is available. The device is able to guarantee operations under a cranking scenario down to VBATT = 3 V and guarantees very low quiescent current under RESET condition.

L9026 has two input pins available connected to two outputs by default, in case of using different or additional outputs, it is managed by SPI.

For a direct control and PWM L9026 has two input pins available connected to two outputs by default, in case of manage different or additional output it is controlled by SPI.

The device is available in two package versions: HTSSOP24 and VFQFPN32. Only for the QFN package 2 additional pins are available for safety reasons. In details, the NRES pin is used to reset internal registers to their default values and the DIS pin is used to disable all channels.
