L99MM70XP数据手册集成电路（IC）的电机驱动器控制器规格书PDF

描述 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.
