L9823 Octal Low-Side Driver for bulb, resistive and inductive loads with serial input control, output protection and diagnostic

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.

Outputs current capability up to 0.5 A
Cascadable SPI control for outputs
Reset function with reset signal or undervoltage at VDD
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 VDD 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
