The L9954 and L9954XP are microcontroller driven, multifunctional door actuator drivers for automotive applications. Up to two DC motors and three grounded resistive loads can be driven with three half bridges and three highside drivers. The integrated standard serial peripheral interface (SPI) controls all operation modes (forward, reverse, brake and high impedance). All diagnostic information is available via the SPI.
The L9954 and L9954XP are microcontroller-driven, multifunctional door actuator drivers designed for automotive applications. These devices feature three half bridges for 1.5A loads and one or two highside drivers for 6A or 1.5A loads, respectively, suitable for driving mirror axes and defroster circuits. The integrated standard serial peripheral interface (SPI) allows a microcontroller to control all operation modes, including forward, reverse, brake, and high impedance states, while providing access to diagnostic information.
