L99MM70XP：Integrated microprocessor driven device intended for LIN controlled exterior mirrors
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.
Key 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
