Mechatronic mirror driver – L99MM70XP Driving the actuators of today’s high-end exterior rear-view mirrors requires many wires, up to 20 cables. Since the mirror joint may have a limited space for the harness, a mechatronic approach using a LIN-bus interface can be the most appropriate way to minimize wiring harness complexity. The L99MM70 is ST’s latest development supporting such a mechatronic approach and offers a flexible and scalable system solution when combined with an STM8A. 5 V low-drop voltage regulator for microcontroller supply (150 mA) Embedded LIN 2.1 (SAEJ2602) transceiver Independent...
