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.
