TDK launches new HVC 5481G in compact 5 × 5mm PQFN32 package
2025-04-18

Suitable for LIN controlled automotive blowers, pumps, and fans in heat exchange systems*
Intelligent BLDC actuators that can also be used for seats, doors, tailgates, and charging doors*
Fully support vector control (FOC) algorithm to achieve low noise and efficient operation

TDK Corporation has further expanded the functionality of its Micronas HVC 5x embedded motor controller series in the automotive application field by launching the new HVC 5481G. HVC 5481G is a programmable Soc gate driver chip used to control an external power bridge with 6 N-channel FETs to drive various actuators, fans, and pumps* The HVC 5481G sample is now available on the market and is expected to begin mass production in 2026.

HVC 5481G SoC is compatible with existing HVC 5x series software and integrates an ARM with 64 KB flash memory and 8 KB SRAM ® Cortex ®- M3 CPU。 It can directly draw power from the 12V car power rail and integrates LIN transceiver to achieve communication function. IC supports multiple motor control algorithms, including sensorless 6-step commutation using BEMF detection and single shunt FOC algorithm. The device is equipped with 7 universal IO pins, an internal timer, and a capture comparison register, which can seamlessly interface with Micronas Hall effect or TDK TMR sensors.

The HVC 5481G adopts a compact 5 × 5 mm PQFN32 package and is certified according to the first level standard of AEC-Q100, providing a reliable and efficient solution for medium power BLDC applications. With its sturdy and durable design and advanced functional features, HVC 5481G is an ideal choice for automotive and industrial applications, ensuring high performance and adaptability of the system.
