TRK-S12VR-WLFT
Development Platform
Window lift and relay-based DC motor control
reference design
Target Applications
Overview
• Roof panel systems
• Power-operated window systems
• Partition systems
The S12 MagniV S12VR portfolio of mixed-signal microcontrollers (MCUs) streamlines
• Relay-based DC motor control
automotive engineering by offering smart, optimized integration of high-precision analog
components combined with the proven S12 MCU. The S12VR family is the first set of system
in package devices in the portfolio based on the LL18UHV process technology targeting both
automotive and industrial anti-pinch window lift, power sun roof modules, LIN controlled relay
drivers, smart actuators, relay-based DC Motors and other space-constrained relay-based DC
motor control applications.
This low-cost reference design showcases the main advantages of the MagniV S12VR 16-bit
MCU to drive relay-based DC motors, some applications are window lifters for passenger door
and sun roof systems. The solution features a low amount of external components, and a
simple design where all the components are placed on top side. It also manages high voltages
of 8 to 24 volts.
