L9953LXP Door actuator driver Features Three half bridges for 0.75A loads (R =1600m) DSon Two configurable high side driver for up to 1.5A load (R =500m) or 0.35A load DSon (R =1800m) on One full bridge for 6A load (R =150m) on PowerSSO-36 One highside driver for 6A load (R =100m) on Programmable soft start function to drive loads Applications with higher inrush currents (i.e. current >6A, >1.5A) Door actuator driver with bridges for door lock, Very low current consumption in standby mode mirror axis control, mirror fold and highside (I < 6A typ T 85 C) driver for mirror defroster and two 10W-light S j bulbs and/or LEDs. All outputs short circuit protected Current monitor output for highside OUT1, Description OUT4, OUT5 and OUT8 All outputs over temperature protected The L9953LXP is a microcontroller driven multifunctional door actuator driver for automotive Open-load diagnostic for all outputs applications. Up to three DC motors and three Overload diagnostic for all outputs grounded resistive loads can be driven with five Separated half bridges for door lock motor half bridges and three highside drivers. The integrated standard serial peripheral interface PWM control of all outputs (SPI) controls all operation modes (forward, Charge pump output for reverse polarity reverse, brake and high impedance). All protection diagnostic informations are available via SPI. Table 1.
