L9953 Door actuator driver

The L9953 and L9953XP are microcontroller driven multifunctional door actuator driver for automotive applications. Up to three DC motors and three grounded resistive loads can be driven with five half bridges and three highside drivers. The integrated standard serial peripheral interface (SPI) contr.

L9953 Features

* One full bridge for 6A load (Ron=150mΩ)

* 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,
