Sales Briefcase
  • L9959S/L9959U and L9959T are single and dual integrated H-bridges for resistive and inductive loads featuring output current direction and supervising functions.

    The PowerSSO24 houses one full H-Bridge, while the PowerSSO36 houses both two H-Bridges that can work in parallel, through independent input driving commands, and one full H-bridge, by improving PCB footprint design versus different target applications.
    Target application ranges from throttle control actuators to exhaust gas recirculation control valves in automotive domain to a more general use to drive DC and Stepper motors.

    Key Features

    • Full path RDSONless than 540 mΩ
    • Continuous load current > 3 A
    • Operating battery supply voltage 5 V to 28 V
    • Operating VDDsupply voltage 4.5 V to 5.5 V
    • All ECU internal pins can withstand up to 18 V
    • Output switching frequency up to 11 kHz
    • Monitoring of VDDsupply voltage
    • SPI programmable output current limitation from 5 A to 8.6 A (in 3 steps)
    • Over temperature and short circuit protection
    • Full diagnosis capability
    • Fast switch-off open-drain input/output
    • Current-monitoring with current feedback output signal CF
    • SPI-interface for configuration and diagnosis
    • Error history in second diagnosis register
    • Two independent enable pins: "/ABE" and "DIS"
    • Control of power stages by SPI or two input signals, PWM and DIR (configurable via SPI)
    • Logic levels 5 V compatible
    • Conformity to improved EMC requirements due to smart H-bridge switching
