Description

L9969S/L9969U and L9969T 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.

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.
