Power Switch Lo Side 0.5A 24-Pin SO T/R

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
