Description

L9026

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.
