STMicroelectronics L99MOD51XP Multi-Output Driver

STMicroelectronics L99MOD51XP Multi-Output Driver is a microcontroller-driven multifunctional actuator driver for automotive applications. Up to two DC motors and two grounded resistive loads can be driven with three half-bridges and two 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

  • One half bridge for 7.4A load (RDSon = 150mΩ)
  • Two half bridges for 5A load (RDSon = 200mΩ)
  • Two high-side drivers for 1.25A load (RDSon = 800mΩ)
  • Programmable soft-start function to drive loads with higher inrush currents (for example, current >7.4A, >5A, >1.25A)
  • <3μA, typ., Tj ≤85°C low current consumption in standby mode
  • All outputs short-circuit protected
  • Current monitor output for all high-side drivers
  • All outputs over-temperature protected
  • Open-load diagnostic for all outputs
  • Overload diagnostic for all outputs
  • Programmable PWM control of all outputs
  • Charge pump output for reverse polarity protection

Applications

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