Product overview

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.
  • All 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
