serial input control, output protection and diagnostic
Datasheet - production data
'!0'03
SO24
Features
 Outputs current capability up to 0.5 A
 Cascadable SPI control for outputs
 Reset function with reset signal or
undervoltage at V_DD
 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)
 Single V_DD logic supply
 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.
