The L99MD02 IC is a 6 x half bridge driver for automotive applications. The device is intended to drive DC-motors. It is possible to drive 3 DC-motors simultaneously or up to 5 DC-motors sequentially.

The integrated 24 bit standard serial peripheral interface (SPI) controls all outputs and provides diagnostic information: normal operation, open-load in on-state, overcurrent, temperature warning and overtemperature.

Key features
  • 6 half bridges
  • RON= typ.0.9 Ω (HS), 0.64 Ω (LS) at Tj= 25 °C
  • Current limit of each output at minimum 0.8 A
  • Internal PWM generation
  • PWM mode option for all half bridges for hold current
  • Two current monitor outputs
  • SPI interface for data communication
  • Temperature warning
  • All outputs overtemperature protected
  • All outputs short circuit protected
  • VCCsupply voltage 3.0 to 5.3 V
  • Very low current consumption in standby mode typ. 5 μA
  • VSoperating range compliant: 6 – 18 V
