About

Scalable solutions for automotive body electronics

Automotive body electronics manage the comfort, access, and motion functions that define modern vehicle interiors. Key application areas include car access, auxiliary motor control for window, wiper, roof, and seat systems, seat comfort, and door & closure systems — each requiring high-quality, scalable semiconductors.

As vehicle body electronics evolve, scalability, low power consumption, and reliable communication become essential. Infineon's comprehensive automotive body electronics portfolio — spanning power ICs, MOSFETs, microcontrollers, and integrated system ICs — is designed for the demanding automotive environment and backed by deep system know-how and dedicated design support to help accelerate your time to market. 

Secure and reliable automotive car access electronics

Automotive car access systems control how drivers and passengers enter, start, and secure their vehicles. Modern implementations include passive entry and passive start (PEPS), remote keyless entry (RKE), immobilizers, NFC-based digital car keys, and ultra-wideband (UWB) ranging for precise localization.

These systems demand high security, low-power operation, and reliable authentication. Infineon offers a dedicated semiconductor portfolio for automotive car access applications — including security controllers, UHF and UWB transceivers, and system ICs trusted by vehicle manufacturers worldwide.

Smart seat control and comfort electronics in vehicles

Automotive seat control and comfort electronics manage electrically adjustable functions, from seat position adjustment to lumbar support, heating, ventilation, and massage. As vehicles integrate more comfort electronics, the semiconductors managing seat systems must be efficient, compact, and highly reliable.

Infineon's portfolio for automotive seat comfort and control includes motor drivers for multi-axis seat adjustment, LIN-connected system ICs, and Hall-effect sensors for accurate position detection. Solutions are optimized for low quiescent current, EMC compliance, and automotive safety standards — enabling intelligent seat comfort electronics across all vehicle segments.

Smart e-mirror and windshield wiper solutions in body electronics

E-mirror modules and windshield wiper systems are safety-relevant exterior visibility functions in automotive body electronics — addressing key design challenges for Tier 1 suppliers and OEMs.

E-mirror modules
Infineon's System Basis Chip (SBC) integrates system supply (LDO and DC/DC), LIN communication, diagnostics, switching, and fail output in a single device — minimizing PCB space and power dissipation. Scalable single and multi half-bridge ICs with integrated MOSFETs and LED drivers support mirror positioning, folding with memory, side and blind spot indicators, and heating with low quiescent current across multi-platform vehicle architectures.

Windshield wiper systems
Infineon supports brushed DC and BLDC wiper motor architectures. Single half-bridge ICs deliver protected high-current PWM drives with overcurrent, overvoltage, and overtemperature protection. 32-bit motor control SoCs with integrated H-bridge drivers enable functional safety and energy-on-demand operation. GMR-based (TLE5012) and dual-channel TMR angle sensors achieve <1° angular error over temperature in ISO 26262-ready designs. High-precision Hall switches complete the motor commutation solution.
