製品概要
概要
The L9026 is an eight-channel IC, with 2 fixed HS drivers and 6 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, over-temperature detections. The 8 output channels can be either driven by SPI or by 2 dedicated parallel inputs. Limp home functionality is also featured, which allows using 2 selected drivers in particular 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 cranking scenario down to VBATT = 3 V and guarantees very low quiescent current under RESET condition.
A serial peripheral interface (SPI) is used for control and configuration of the loads as well as of the device; besides, status feedback of all diagnostic functions is provided. For direct control and PWM there are two input pins available: these are connected to two defined outputs by default, but additional or different output mapping can be controlled by SPI.
As reported above 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.
