Infineon Technologies said it has launched the integrated power management IC "OPTIREG TLE9744QK" for high-voltage traction inverters for electric and hybrid vehicles.
The product integrates power supply functions, resolver excitation, and a dedicated safety engine to simplify traction inverter ECU design and replace multiple discrete components with a single-chip solution.
Infineon said the product reduces system cost and complexity, cuts PCB area by up to 70%, and continuously monitors phase current, DC link voltage, MCU status, and gate driver status with ISL.
Infineon Technologies said it has launched the integrated power management IC (PMIC) "OPTIREG TLE9744QK" for high-voltage traction inverters in electric and hybrid vehicles. "OPTIREG TLE9744QK" integrates power supply functions, resolver excitation, and a dedicated safety engine.
Infineon said the integration simplifies the design of traction inverter electronic control units (ECUs). According to the company, it can address the complexity of having to provide multiple isolated power rails for the MCU, communication modules, and sensors.
According to Infineon, TLE9744QK replaces multiple discrete components with a single-chip solution. This reduces system cost and complexity, significantly cuts the bill of materials (BOM), and reduces PCB area by up to 70% based on the devices being replaced. It also improves system reliability and functional safety.
Infineon said OPTIREG TLE9744QK uses an integrated implementation based on embedding key peripheral functions directly in silicon. It also said OPTIREG TLE9744QK includes an internal resolver excitation signal generation function, eliminating the need for an external resolver driver as well as external monitoring circuits.
Infineon said the product provides broad power supply compatibility for a wide range of microcontrollers and also for a wide range of gate drivers. It added that it provides functional interoperability between the microcontroller and the gate driver, allowing existing MCU platforms to be used depending on flexibility, and that existing MCU platforms can be used without large-scale hardware redesigns, helping shorten time to market.
The company also said the product supports off-board sensor power supply, further increasing design flexibility for system optimization.
Infineon said the product is equipped with an independent hardware architecture and integrated safety logic (ISL, Integrated Safety Logic). ISL continuously monitors phase current, DC link voltage, MCU status, and gate driver status, and the company said these functions help strengthen system reliability and system safety.
OPTIREG TLE9744QK is currently available. Samples are also available on request, and evaluation boards are available on request. Reference designs are also available on request, and documentation is available on request. Software is available on request, and development tools are available on request.
