Solution Description
This solution describes a cost-effective mini zone controller for automotive side mirror applications using an SPC58 2B general-purpose automotive 32-bit Power Architecture MCU and an L99DZ200G multi-output driver that controls the folding/unfolding, x/y-axis mirror inclination, electrochromic dimming, and defrosting functions.
The L99DZ200G integrates a current monitor to accurately detect the mechanical endstop limits. The L99DZ200G can also drive two strings of LEDs for turn signals or puddle lights.
Moreover, external encoders can be added to determine the effective position of the side mirrors and send the acquired data to the MCU to implement safety features or create a specific “positioning” profile for each vehicle user.
An optional feature allows the mini zone controller to be driven through CAN messages from a host ECU.

Key Product Benefits
SPC582B60E1 - 32-bit Power Architecture MCU for general-purpose automotive applications
The SPC582B60E1 benefits from the comprehensive SPC5 development ecosystem.
Designed in compliance with ISO 26262 specifications, SPC58 2B Line MCUs support the ASIL-B safety standard and feature a high number of ISO CAN-FD channels as well as numerous power and performance enhancements.
L99DZ200G - Automotive-grade multi-output driver with LIN and HS-CAN connectivity
The L99DZ200G is a door zone system IC integrating LIN and HS CAN transceivers; the integration of seven high-side drivers allows to supply LEDs and bulbs. Four half bridges can control up to three DC motors; eight external MOS transistors (4 for each of the 2 H-bridge drivers) can be driven and two low-drop voltage regulators are also embedded.
