IN Brief:
- MGJ2T2 is an isolated DC/DC converter series for high voltage SiC gate drive circuits.
- SCI36LT combines 6DoF inertial sensing, passive components and an MCU in one LGA package.
- Murata plans to publish fuller electrical specifications for both products during electronica in November.
Murata will introduce a new isolated DC/DC converter for silicon carbide gate drive circuits and a 6DoF inertial sensor with integrated processing at electronica 2026 in Munich.
The MGJ2T2 series is intended to supply SiC MOSFET gate drivers in energy storage, power distribution, motor drives and EV charging systems. Murata has not yet published the full voltage, power and isolation ratings, but the device is being positioned around high isolation performance and resistance to electrical noise generated by fast switching power stages.
A high side switch in a bridge does not remain referenced to controller ground because its source or emitter moves with the switching node. The gate driver still needs a stable local supply, so an isolated converter has to transfer power across a barrier that is exposed to rapid voltage changes while keeping disturbances away from the low voltage control electronics.
Parasitic capacitance across that isolation barrier allows displacement current to flow whenever the switching node changes voltage. SiC devices can switch with high dV/dt, so even a small capacitance can couple substantial transient current into the control side. The resulting disturbance can affect gate timing, increase electromagnetic interference or place additional stress on surrounding components.
Murata’s existing MGJ1T range shows how the company has approached those constraints in earlier gate drive supplies. The 1 W series is production tested to 6 kV DC, has typical isolation capacitance of 2.5 pF and is characterised for common mode transient immunity above 200 kV/µs. Those figures do not describe MGJ2T2, whose detailed ratings remain unpublished, but they show the electrical parameters that determine how an isolated supply behaves beside a fast SiC switch.
The SCI36LT tackles a different interface problem by combining six axis inertial sensing, passive components and an MCU in one LGA package. The integrated processor can run Murata’s sensor fusion algorithms locally, producing orientation information in pitch, roll and yaw rather than requiring the host system to combine raw accelerometer and gyroscope channels.
Accelerometers and gyroscopes contribute different errors to an orientation estimate. Gyroscope data can drift as small rate errors accumulate over time, while accelerometers respond to vibration and linear motion as well as gravity. Sensor fusion combines both inputs so each can compensate for limitations in the other, with calibration, filtering and sample timing affecting the final result.
Moving that processing inside the sensor module reduces the amount of external circuitry and host software needed to produce an orientation output. It also keeps acquisition timing and the fusion algorithm close together, avoiding additional latency or timing variation introduced when several raw channels have to be transferred elsewhere before they are combined.
Murata is presenting SCI36LT within its AI and robotics portfolio, but it has not yet published measurement range, noise density, bias stability, interface options or environmental limits. Those values will determine how the device fits robotics, industrial motion sensing, vehicle systems or other embedded applications once the complete data sheet is available.
MGJ2T2 and SCI36LT place difficult interface functions closer to the component that depends on them. MGJ2T2 supplies isolated power around a fast switching gate driver, where capacitance and transient immunity affect switching behaviour, while SCI36LT performs part of the sensing computation inside the package rather than passing every raw channel to an external processor.
That integration can simplify the surrounding circuit, but it also makes the internal characteristics of the module more important. A gate drive converter with unsuitable parasitic behaviour can undermine the advantages of the SiC device it powers, while an inertial module with weak calibration or noise performance can limit the value of local sensor fusion.
Murata plans to publish further MGJ2T2 and SCI36LT specifications during electronica, which runs from 10 to 13 November. Until those ratings are available, the products can be assessed by their architecture and intended applications, but detailed comparisons on isolation, power, sensing range and accuracy should wait for the final data sheets.
