Product overview
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.
