L9950TR Integrated Circuit Chip Microcontroller Driven Multifunctional Door Actuator Driver
The L9950TR is a microcontroller-driven multifunctional door actuator driver designed for automotive applications. This versatile IC can drive up to five DC motors and five grounded resistive loads using six half bridges and five highside drivers. All operation modes (forward, reverse, brake, and high impedance) are controlled through the integrated standard serial peripheral interface (SPI), while comprehensive diagnostic information is accessible via the same interface.
