Door Actuator Driver 36-Pin PowerSO T/R

The L9954 and L9954XP are microcontroller driven multifunctional door actuator driver 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 informations are available via SPI.

Three half bridges for 1.5A load (R_on=800m )

One highside driver for 6A load (R_on=100m )

Two highside drivers for 1.5A load (R_on=800m )

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

Very low current consumption in standby mode (I_S < 6µA typ; T_j = 85 °C)

All outputs short circuit protected

Current monitor output for highside OUT1, OUT4, OUT5 and OUT6

All outputs over temperature protected

Open load diagnostic for all outputs

Overload diagnostic for all outputs

PWM control of all outputs

Charge pump output for reverse polarity protection
