Infineon has released the OPTIREG TLE9744QK, a power management integrated circuit designed for high-voltage traction inverters. The device aims to streamline inverter architecture by integrating complex safety and supply functions.
Why it matters
The chip consolidates multiple components to reduce inverter board area and total parts count, which helps manufacturers optimize complex electronics. By providing an independent safety path, the device supports critical safety standards for high-voltage systems.
The chip operates in a voltage range of 4 V to 36 V with a quiescent current of 50 µA. It functions across an operating temperature range of -40° C to 150° C and meets ASIL-D safety requirements.
The players
Infineon
Infineon is a global semiconductor manufacturer specializing in power systems and automotive electronics.
The details
The device incorporates two buck/boost pre-regulators alongside linear post-regulators to manage sensors and communication modules. A redundant supply input ensures the Integrated Safety Logic maintains functionality even if the main low-voltage supply fails.
Timeline
Infineon released the OPTIREG TLE9744QK on September 21, 2026.
The product is planned to remain available until at least 2038.
The Tech Race
This component reflects the industry-wide move toward higher integration to save space in electric vehicle traction systems. It replaces bulkier discrete component assemblies with a single, highly efficient architecture.
For developers and automotive engineers, this chip simplifies design complexity and reduces physical footprint requirements on circuit boards. The long-term availability of the component through 2038 provides stability for long-cycle automotive manufacturing projects.
The takeaway
By utilizing integrated safety logic, manufacturers can achieve higher safety ratings without the added bulk of additional external components. This shift toward high-density power management is essential for maintaining the efficiency of modern high-voltage traction systems.
