Description
L9959S and L9959T are a 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 two H-Bridges that can
work in parallel, through independent input driving
commands.
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.
