L9959 Single and dual PMOS high-side H-bridge Datasheet - production data Current-monitoring with current feedback output signal CF SPI-interface for configuration and diagnosis Error history in second diagnosis register Two independent enable pins:/AB and DI Control of power stages by SPI or two input 0 03 signals, PWM and DIR (configurable via SPI) 0 03 Logic levels 5 V compatible PowerSSO24 PowerSSO36 Conformity to improved EMC requirements due to smart H-bridge switching Description Features L9959S/L9959U and L9959T are single and dual Full path R less than 540 m DSON integrated H-bridges for resistive and inductive Continuous load current > 3 A loads featuring output current direction and supervising functions. Operating battery supply voltage 5 V to 28 V The PowerSSO24 houses one full H-Bridge, while Operating V supply voltage 4.5 V to 5.5 V DD the PowerSSO36 houses both two H-Bridges that All ECU internal pins can withstand up to 18 V can work in parallel, through independent input Output switching frequency up to 11 kHz driving commands, and one full H-bridge, by improving PCB footprint design versus different Monitoring of V supply voltage DD target applications. SPI programmable output current limitation from 5 A to 8.6 A (in 3 steps) Target application ranges from throttle control actuators to exhaust gas recirculation control Over temperature and short circuit protection valves in automotive domain to a more general Full diagnosis capability use to drive DC and Stepper motors.
