Product overview

Description

The L99MM70XP is a microcontroller driven multifunctional system ASSP dedicated for LIN controlled wing mirror applications. The device contains a voltage regulator to supply the microcontroller and a LIN2.1 physical layer. Up to 3 DC motors and five grounded resistive loads can independently be driven with four (five) half bridges and five high-side driver. The EC-glass control block provides overvoltage protection with a fast discharge path versus GND and a negative discharge path for future EC-glass characteristics. The integrated ST SPI controls all operation modes (forward, reverse, brake and high-impedance) and provides all the diagnostic information.

  • All features

    • 5 V low-drop voltage regulator (150 mA max.)
    • Embedded LIN transceiver: 2.0/2.1 compliant and SAEJ2602 compatible
    • Independent control of mirror adjustment motors
    • One full bridge for 3 A load (Ron= 300 mΩ)
    • Two (three) half bridges for 0.5 A load (Ron= 1.6 Ω)
    • One configurable high-side driver for up to 1.5 A load (Ron= 500 mΩ / 10 Watt bulb control, or 1600 mΩ / LED control)
    • Two high-side driver for 0.5 A load (Ron= 1600 mΩ)
    • One low-side driver 0.5 A load (Ron= 1600 mΩ) used as half bridge with high-side driver for independent mirror axis control
    • One high-side driver for 6 A load (Ron= 90 mΩ)
    • One high-side driver for 0.5 A load (Ron= 1600 mΩ) to supply an external MOSFET to drive an EC-glass
    • Integrated EC glass control via an external MOSFET with fast discharge path: EC-glass can be discharged to GND or to -1 V
    • Programmable soft start function to drive loads with higher inrush currents (>6 A, >1.5 A)
    • Very low current consumption modes
    • All outputs short-circuit and overtemperature protected
    • Two thermal shutdown thresholds and early temperature warning
    • Current monitor output for all high-side drivers
    • Open-load diagnostic for all outputs
    • Overload diagnostic for all outputs
    • 3 PWM control signals for all outputs
    • Charge pump output for active reverse polarity protection via an external N-channel MOSFET
    • STM standard serial peripheral interface for control and diagnosis
    • INH input for external CAN transceiver
