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.

Key features
  • Overload diagnostic for all outputs
  • Open-load diagnostic for all outputs
  • Charge pump output for reverse polarity protection
  • PWM control of all outputs
  • Current monitor output for high-side OUT1, OUT4, OUT5 and OUT6
  • All outputs short circuit protected
  • Three half bridges for 0.75 A loads (RDSon = 1600 mΩ)
  • One high-side driver for 6 A load (RDSon = 100 mΩ)
  • Two configurable high-side driver for up to 1.5A load (RDSon = 500 mΩ) or 0.35 A load (Ron = 1800 mΩ)
  • Very low current consumption in standby mode (IS < 6 μA typ; Tj = 85 °C)
  • All outputs over temperature protected
  • Programmable soft start function to drive loads with higher inrush currents (i.e. current > 6 A, current > 1.5 A)
