L9959 Single and dual PMOS high-side H-bridge Datasheet - production data '!0'03 PowerSSO24 '!0'03 PowerSSO36  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 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 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 ...
