E-L9826TR

Octal protected low-side driver with diagnostic and serial/parallel input control

STMicroelectronics 

L9826

Octal protected low-side driver with diagnostic

and serial/parallel input control

Features

■ 8 channels low side driver with 450 mA output

current capability

■ Typical RDSON 1.5  at TJ = 25 °C

■ Parallel control for output 1 and 2

■ SPI control on all outputs

■ Reset function

■ Diagnostic through 8 bit SPI

■ Intrinsic output voltage clamping 50 V (Typ)

protection for inductive load drive

■ Short circuit current limitation and thermal

shutdown for outputs 1 and 2

■ Overcurrent and short circuit shutdown for

outputs 3 to 8

Description

The L9826 is a protected octal low-side driver IC

designed for the automotive environment.

SO20

'!0'03

The 8 -bit serial peripheral interface (SPI) is able

to control the device's eight channels and to

provide its load's diagnosis. In addition output 1

and 2 can also be controlled through dedicated

input pins NON1 and NON2.

Overcurrent and short-circuit protections are

present as well as the output voltage clamping

which is able to protect the L9826 during

operation with inductive loads.
