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.

Features

● 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
