L9954 Door actuator driver

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) cont.

L9954 Features

* Three half bridges for 1.5A load (Ron=800mΩ)

* One highside driver for 6A load (Ron=100mΩ)

* Two highside drivers for 1.5A load (Ron=800mΩ)

* Programmable softstart function to drive loads with higher inrush currents (i.e. current >6A, >1.5A)

* Very low current consumption in s
