1 / 68 page  September 2013 Doc ID 022637 Rev 2 1/68 1 L99MM70XP Integrated microprocessor driven device intended for LIN controlled exterior mirrors 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 m) ■ Two (three) half bridges for 0.5 A load (Ron =1.6 ) ■ One configurable high-side driver for up to 1.5 A load (Ron = 500 m/ 10 Watt bulb control, or 1600 m / LED control) ■ Two high-side driver for 0.5 A load (Ron =1600m) ■ One low-side driver 0.5 A load (Ron =1600m) used as half bridge with high- side driver for independent mirror axis control ■ One high-side driver for 6 A load (Ron =90 m) ■ One high-side driver for 0.5 A load (Ron =1600m) 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 Applications ■ LIN controlled mirror 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. Table 1.
