Door Actuator Driver 36-Pin PowerSSO T/R

The L9954LXP is a 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 high-side 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 0.75 A loads (R_DSon = 1600 mO)

Two configurable high-side driver for up to 1.5A load (R_DSon = 500 mO) or 0.35 A load (R_on = 1800 mO)

One high-side driver for 6 A load (R_DSon = 100 mO)

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

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

All outputs short circuit protected

Current monitor output for high-side 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
