TDK Corporation extends the power capability of its Micronas HVC 5x embedded motor controller family with the new HVC 5481G for automotive applications. The HVC 5481G is a programmable gate driver system-on-chip (SoC) for control of an external power bridge with 6 N-channel FETs to drive actuators, fans, and pumps. Samples of the HVC 5481G are available now and production will begin in 2026.
The HVC 5481G SoC is compatible to the existing HVC 5x family software, integrating an ARM® Cortex®-M3 CPU with 64 KB flash memory and 8 KB SRAM. It operates directly from the 12 V automotive supply rail and integrates a LIN transceiver for communication. The IC supports various motor control algorithms from sensor-less 6-step commutation using BEMF detection to single shunt FOC. The device includes 7 general-purpose IO pins, internal timers, and capture compare registers, allowing seamless interfacing with the Micronas Hall-effect or TDK TMR sensors.
Main applications
- Blowers, pumps and fans in automotive applications.
- LIN based seat movers.
- Smart higher power actuators for doors and lift-gates.
Available in a compact 5 x 5 mm PQFN32 package and certified according to AEC-Q100 Grade 1 standards for automotive, the HVC 5481G delivers a reliable and efficient solution for medium power BLDC applications. Its robust design and advanced features make it the device of choice for automotive and industrial applications, ensuring high performance and adaptability.
