L9823

Octal low-side driver for bulb, resistive and inductive loads with

serial input control, output protection and diagnostic

Datasheet

Features

 Outputs current capability up to 0.5 A

 Cascadable SPI control for outputs

 Reset function with reset signal or

 Programmable intrinsic output voltage

clamping at typ. 50 V for inductive switching

 Overcurrent shutdown with latch-off for every

write cycle (SFPD = low)

 Independent thermal shutdown of outputs

(SOA Protection)

 Output status data available on the SPI using

8-bit I/O protocol up to 3.0 MHz

 Low standby current with reset = low (typ.

35 µA @ VDD)

 Open load detection (outputs off)

 High EMS immunity and low EME (controlled

output slopes)

 Full functionality of the remaining device at

negative voltage drop on outputs (-1.5 V or

-3.0 A)

 Output mode programmable for sustained

current limit or shutdown

Description

L9823 is a octal low-side driver circuit, dedicated

for automotive applications.

Output voltage clamping is provided for flyback

current recirculation, when inductive loads are

driven.

Chip select and cascadable serial 8-bit Interface

for outputs control and diagnostic data transfer.
