Description

The L9953 and L9953XP are microcontroller driven multifunctional door actuator driver for automotive applications.

Key Features

  • One full bridge for 6A load (Ron=150mΩ)
  • Three half bridges for 1.5A load (Ron=800mΩ)
  • One highside driver for 6A load (Ron=100mΩ)
  • Two highside drivers for 1.5A load (Ron=800mΩ)
  • Programmable softstart function to drive loads with higher inrush currents (i.e. current >6A, >1.5A)
  • Very low current consumption in stand-by 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
