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.
