L9959T-TR-D

马达/运动/点火控制器和驱动器 Single / Dual PMOS High-side H-bridge

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.
