AEK-MOT-MR200G1

The AEK-MOT-MR200G1 is designed as a mini zone controller for the side mirror application.

The AEK-MOT-MR200G1 hosts an SPC582B60E1 chorus 1M microcontroller and an L99DZ200G automotive-grade multioutput driver.

Thanks to the integrated L99DZ200G, the board allows controlling different functions related to a vehicle side mirror: folding, unfolding, X-Y mirror inclination, electrochromic dimming, and heating.

The L99DZ200G integrates the current monitor (high-side only) for X-Y, folding/unfolding, and LED outputs, in order to detect the mechanical end stop switches.

Through dedicated connectors, the AEK-MOT-MR200G1 supports external encoders, which detect the effective position of the side mirror and send the acquired data to the SPC582B60E1. This information can be used to implement safety features or, for example, to create and store a specific profile for each vehicle user.

The board also allows driving two strings of LEDs (to be used, for example, for turn signals or puddle lights).

In the AutoDevKit software package, we have included two AEK-MOT-MR200G1 evaluation demos that you can use for your own project development.

The first demo is preloaded on the AEK-MOT-MR200G1 and, once running, it performs an activation sequence of the board outputs (motors, heater, electro-chrome voltage (ECV)). It shows how to drive up to three 12 V DC motors (one up to 7.5 A and the other two up to 500 mA), turn on/off two LED strings (at 12 V, one up to 1.5 A and the other up to 700 mA), activate the heater and the electro-chrome functions.

In addition, the downloaded firmware enables board control through CAN messages received from a host ECU, after flashing the second demo on an AEK-MCU-C4MLIT1. At the end of the first demo sequence, the board waits for 8 seconds to receive CAN messages. In case of no message reception, it restarts the automatic sequence from the beginning. To transmit control CAN messages, connect the AEK-MCU-C4MLIT1 to the AEK-MOT-MR200G1 and press user button 1 (SW_1) or user button 3 (SW_3).

To program the onboard SPC582B60E1 microcontroller, connect the SPC5-UDESTK to the JTAG connector, and connect the board to a PC via USB and run the PLS UDE to flash the code.
