1 / 49 page This is information on a product in full production. October 2015 DocID027540 Rev 2 1/49 L9959 Single and dual PMOS high-side H-bridge Datasheet - production data Features Full path RDSON less than 540 mΩ Continuous load current > 3 A Operating battery supply voltage 5 V to 28 V Operating VDD supply 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 VDD supply 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 Description 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.
