Japanese producer TDK Electronics has prolonged the ability functionality of its Micronas high-voltage microcontrollers (HVC) 5x embedded motor controller household with its new HVC 5481G for automotive purposes.
The chips are designed for native interconnect community (LIN)-controlled automotive blowers, pumps and followers in thermal techniques. They’ll additionally energy sensible brushless DC motor (BLDC) actuators in seats, doorways, liftgates and charge-port doorways.
The HVC 5481G is a programmable gate driver system-on-chip (SoC) for management of an exterior energy bridge with 6 N-channel FETs to drive actuators, followers, and pumps. Samples of the HVC 5481G can be found now and manufacturing will start in 2026.
The HVC 5481G SoC is appropriate with TDK’s current HVC 5x household software program, integrating an ARM Cortex-M3 central processing unit (CPU) with 64 kb flash reminiscence and eight kb SRAM. It operates instantly from the 12 V automotive provide rail and integrates a LIN transceiver for communication.
The IC helps varied motor management algorithms from sensor-less 6-step commutation utilizing BEMF detection to single shunt Discipline Oriented Management (FOC) algorithms for low noise and excessive effectivity. The machine contains seven general-purpose IO pins, inside timers, and seize evaluate registers, permitting seamless interfacing with the Micronas Corridor-effect or TDK TMR sensors.
The HVC 5481G is obtainable in a compact 5 x 5 mm PQFN32 bundle and licensed in line with AEC-Q100 Grade 1 requirements for automotive for medium-power BLDC purposes.
