Integrated Microprocessor Driven Device 36-Pin PowerSSO T/R

Integrated Microprocessor Driven Device 36-Pin PowerSSO T/R

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.
  • 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 mO)
  • Two (three) half bridges for 0.5 A load (Ron= 1.6 O)
  • One configurable high-side driver for up to 1.5 A load (Ron= 500 mO / 10 Watt bulb control, or 1600 mO/ LED control)
  • Two high-side driver for 0.5 A load (Ron= 1600 mO)
  • One low-side driver 0.5 A load (Ron= 1600 mO) used as half bridge with high-side driver for independent mirror axis control
  • One high-side driver for 6 A load (Ron= 90 mO)
  • One high-side driver for 0.5 A load (Ron= 1600 mO) 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
