HVAC control module
For HVAC control module applications to function seamlessly you need solutions precisely tailored to flap and blower control needs. For instance, dedicated multi half-bridge devices for flap motor control with potentiometer feedback or an embedded bridge driver IC with a current controlled output stage, flexible charge- and discharge current settings and several diagnostic functions to optimize your blower control. Additionally, semi and fully automatic HVAC systems integrate a system/user-interface and graphical display as well as temperature and humidity sensing.
Infineon offers a wide range of products with the exact specifications and functions required to make your HVAC control module application a success. From our high-performance, scalable microcontroller families with industry leading CapSense® technology to create a sleek user interface, to our 32-bit Embedded Power ICs for high precise half- or full-bridge DC and BLDC motor control applications.

Traveo II CYT2B7 series, for instance, offers cutting-edge performance and robust safety features for automotive body applications. This series provides higher response and faster communication with embedded CAN FD & LIN interfaces. Traveo II devices have advanced security features with the introduction of HSM (hardware security module), dedicated Cortex®-M0+ for secure processing, and embedded flash in dual bank mode for FOTA requirements. The 32-bit MCU core system consists of a 160-MHz Arm® Cortex®-M4F Single, 1 MB code flash, 96 KB work flash, and 128 KB SRAM and Arm® Cortex® -M0+for Crypto operations. The family features six power modes that enable ECUs to minimize overall power consumption and cutting-edge security features for secure communication with great scalability in memory size and pin count.
Infineon´s TLE987x family, for instance, enables the implementation of advanced motor control algorithms. The TLE987x family addresses a wide range of smart 3-Phase Brushless DC motor control applications like auxiliary pumps and fans. It provides an unmatched level of integration and system cost to optimize the target application segments. In addition to this, it offers scalability in terms of flash memory sizes (36 kByte to 256 kByte) and MCU system clock frequency (24 to 40 MHz) supporting a wide range of motor control algorithms, either sensor-based or sensor-less. Moreover, the charge pump is capable to drive gate charges up to 150nC per MOSFET under limited conditions. TLE987x uses the same MCU and peripherals as the TLE986x family, 2-Phase driver, enabling design synergies between DC and BLDC motor control applications.
The PSoC® 4 portfolio consists of several families of Arm® Cortex®-M0 and Cortex-M0+ microcontrollers. Most devices in the portfolio include Cypress’ CapSense® technology for capacitive-sensing applications. The PSoC® 4 portfolio includes also a customizable analog front end through programmable analog blocks as well as connectivity options such as CAN.
- NovalithIC™ provides a complete low-ohmic-protected half-bridge in a single package. It can be combined with an additional NovalithIC™ to create an H-bridge or 3-phase bridge as well. The NovalithIC™ family has the capability to switch high-frequency PWM while providing overcurrent, overvoltage and overtemperature protection. The NovalithIC™ family offers cost-optimized solutions for protected high-current PWM motor drives with very low board-space consumption - scaled to your needs.
- Infineon´s multi half-bridge ICs range from 2-fold half-bridge ICs to 12-fold half-bridge ICs. The products include the complete driver and output stage and are designed to drive small DC motors like HVAC flaps. All products are equipped with several diagnostic and protection features.
