Smart power closure system
Manage smart power closure modules in the smallest space, with lowest power dissipation, and low quiescent current
Enhance your designs and overall user experience with smart power modules that include vehicle closure features like power lift gates, power sliding doors, power doors, power tailgates, and power convertible tops. Tested to ensure the highest levels of performance, Infineon offers integrated solutions for efficient and compact smart power closure modules that address challenges in EMC emissions control and support scalable design variants.
Upgrade user experience with advanced smart power closure systems
As one of the direct interfaces to the driver and passengers, automotive closure systems that control the entry and exit points are an important contributor to the user experience and a differentiator for car-makers.
Smart power closure systems include:
- Power lift gate and power boot/trunk, e.g., for accessing the trunk by raising, lowering, and latching the rear access panel on an SUV or sedan, often with hands-free operation
- Power sliding door, e.g., horizontal movement and latching of the side doors of a van, minivan, or other MPV
- Power doors, e.g., self-opening and self-closing driver and passenger doors that allow easy ingress and egress from the vehicle
- Power tailgate, e.g., raising and lowering of the door on the bed of a pickup truck
- Power convertible top, e.g., opening or closing of a soft-top or hard roof panels in a cabriolet
- Sunroof, e.g., fully or partially opening and closing of the sunroof panel
- Electric charging lid, e.g., lid operation including gesture, mechanical, and remote control
- Frunk, e.g., opening and closing of additional storage space on electric vehicles
A range of impressive options for enhanced vehicle accessibility
While electromechanical systems like power windows have been standard options for modern cars, fully electronic smart power closures, such as power lift gates and power sliding door modules, have evolved from optional extras to standard equipment.
This approach offers users several advantages:
- Comfortable, soft stopping motion through PWM motor regulation that avoids the noise and hazard of a hard closure slam improving the user experience
- Providing additional intelligence, robustness, and safety via sense, diagnosis, and protection elements by solid-state solutions
- Control software updated by SOTA, to overwrite control software after production release
High integration of functions and low-power dissipation
To manage smart power closure modules in the smallest space and with the lowest power dissipation and low quiescent current, integration of functions is one of the key factors for design. The Infineon product portfolio is best prepared and offers many product families with high integration.
An additional challenge for the smart power closure module designer is the increasing number of configurable variants driven by a car manufacturer’s platform strategy. To easily support the diverse variants with a single PCB design, scalability within product families has become necessary. Infineon’s TRAVEO™ T2G MCU family provides scalable memory and I/O capabilities to meet OEM platform power closure design requirements. Infineon’s PROFET™ family of smart high-side power switches, for example, offers the most scalable portfolio of high-side switches in the market.
SBC, multi-MOSFET driver ICs and NovalithIC™ technologies at work
The Infineon product portfolio is best prepared and offers many product families with high integration:
- OPTIREG™ SBC (system basic chip) gathers a system supply, communication interface, diagnosis, switching functions, and failsafe output with best-in-class quiescent current in one product
- MOTIX™ multi-MOSFET driver ICs to control up to eight half-bridges (with external MOSFETs) with best-in-class quiescent current
- MOTIX™ single half-bridge ICs, low ohmic protected single half-bridge switch (with integrated MOSFETs)
As with many power motor control designs, one of the critical aspects is controlling EMC emissions during PWM operation. Our products (MOTIX™ multi-MOSFET driver ICs and MOTIX™ single half-bridge ICs (NovalithIC™) include features that avoid the compromise between EMC performance and power dissipation
