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.
