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 Power SSO24 houses one full H-Bridge, while the Power SSO36 houses two H-Bridges that can work in parallel, through independent input driving mands.
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...
