STMicroelectronics L99MOD54XP Multi-Output Driver

STMicroelectronics L99MOD54XP Multi-Output Driver is a microcontroller-driven multifunctional 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 SPI controls all operating modes (forward, reverse, brake, and high impedance). All diagnostic information is available via SPI read.

Features

  • AEC-Q100 qualified
  • Three half bridges for 0.75A loads (RDSon = 1600mΩ)
  • Two configurable high-side drivers for up to 1.5A load (RDSon = 500mΩ) or 0.35A load (RDSon = 1800mΩ)
  • One high-side driver for 6A load (RDSon = 100mΩ)
  • Programmable soft-start function to drive loads with higher inrush currents (for example, current >6A, current >1.5A)
  • <6μA typ; Tj ≤85°C current consumption in standby mode 
  • 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

Applications

  • Motor control (multiple motors with additional loads in high-side configuration)
    • Bulbs
    • LEDs
  • Protected supply
    • Sensors
    • Cameras
