1 / 35 page  September 2013 Doc ID 16185 Rev 3 1/35 1 L9953LXP Door actuator driver Features ■ Three half bridges for 0.75A loads (RDSon=1600mΩ) ■ Two configurable high side driver for up to 1.5A load (RDSon=500mΩ) or 0.35A load (Ron=1800mΩ) ■ One full bridge for 6A load (Ron=150mΩ) ■ One highside driver for 6A load (Ron=100mΩ) ■ Programmable soft start function to drive loads with higher inrush currents (i.e. current >6A, >1.5A) ■ Very low current consumption in standby mode (IS < 6µA typ; Tj ≤ 85 °C) ■ All outputs short circuit protected ■ Current monitor output for highside OUT1, OUT4, OUT5 and OUT8 ■ All outputs over temperature protected ■ Open-load diagnostic for all outputs ■ Overload diagnostic for all outputs ■ Separated half bridges for door lock motor ■ PWM control of all outputs ■ Charge pump output for reverse polarity protection Applications ■ Door actuator driver with bridges for door lock, mirror axis control, mirror fold and highside driver for mirror defroster and two 10W-light bulbs and/or LEDs. Description The L9953LXP is a 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) controls all operation modes (forward, reverse, brake and high impedance). All diagnostic informations are available via SPI.
