Product overview

Description

The L99MD01 is an octal half-bridge driver for automotive applications.

The device is intended to drive DC and/or stepper motors. Using the boost converter it’s possible to drive 4 stepper motors simultaneously. Without boost converter the system is able to run 3 stepper motors in sequential mode or 2 stepper motors simultaneously. The octal half bridge configuration allows also to drive 4 DC-motors simultaneously and 7 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.

  • All features

    • 8 half bridges
    • RON = typ. 0.9 Ω (HS), 0.64 Ω (LS) @ Tj= 25 °C
    • Current limit of each output at min. 0.8 A
    • Intrinsic DC/DC step up converter driving an external MOSFET
    • PWM mode option for all half bridges for hold current
    • Internal PWM generation
    • 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 V – 18 V
