Product Summary

The L9950TR is a Door actuator driver. It is a microcontroller driven multifunctional door actuator driver for automotive applications.Up to five DC motors and five grounded resistive loads can be driven with six half bridges and five highside drivers. The applications of the L9950TR are Door actuator driver with bridges for door lock and safe lock, mirror axis control, mirror fold and highside driver for mirror defroster and four 10W-light bulbs.
