The ASM330LHHG1 automotive-qualified inertial measurement unit (IMU), which operates from -40°C to 125°C, can be mounted in vehicle zones including those where the ambient temperature may be a concern. Combining low-noise sensors, temperature compensation, and a 6-channel synchronized output, the IMU fulfils the industry’s need for greater dead-reckoning accuracy to support navigation and positioning. Today’s cars, vans, and trucks, as well as industrial and agricultural vehicles, can leverage increasingly accurate GNSS positioning technologies for applications such as routing, tracking, navigation, and driver assistance. These new and enhanced systems need high-quality dead reckoning to maintain continuity between satellite updates and provide effective fallback during GNSS outages or corruption, ensuring superior performance and greater resilience. ST’s ASM330LHHG1 meets this need by delivering 3-axis accelerometer and 3-axis gyroscope data through its synchronized output that ensure

STMicroelectronics’ L9963F automotive battery-management IC includes all the features needed to manage lithium battery packs in hybrid (HE) and full electric (FE) vehicles, as well as industrial energy storage systems, and 48V/96V applications. The L9963F brings under-the-skin improvements to the industry-proven L9963E as a fully compatible replacement that requires no hardware or software changes for existing users of the L9963 series. One device can monitor from 4 to 14 stacked cells, thereby addressing applications up to 48V. Connecting multiple ICs permits even larger arrays of up to 31 battery packs with a total of 434 series cells. Coulomb counting inside the L9963F supports pack overcurrent detection in both ignition on and off states. A fully redundant cell-measurement path, with ADC swap, provides enhanced safety and enables limp-home functionality. The L9963F can take its power from the monitored battery and integrates circuitry to generate stable internal references and ensu

STMicroelectronics has introduced two 100-Watt VIPerGaN high-voltage converters, extending wide-bandgap energy savings throughout domestic appliances, building and home automation, smart lighting, and consumer products including televisions and device chargers. The new converters include the VIPerGaN100W, with 3.5A drain current limit, while the VIPerGaN100WB has a 4.2A current limit for handling short-term peak power up to 125W. The extra flexibility saves designers over-specifying power circuitry in equipment containing inductive loads like solenoid valves or motors, such as in coffee makers, small appliances, and air-conditioners. Both converters are compatible with the universal AC input voltage range, from 85V to 265V, and will deliver 100W from 185V supply. The 700V gallium-nitride (GaN) power transistor in each converter ensures ruggedness and reliability, with extremely low RDS(on) of 0.27mΩ that helps achieve great thermal performance.

STMicroelectronics has announced two new high-speed half-bridge gate drivers that bring gallium-nitride (GaN) efficiency, thermal performance, and miniaturization to a broad range of power and motion-control applications. The STDRIVEG212 and STDRIVEG612 deliver tightly controlled 5V gate-drive signals to enhanced-mode GaN HEMTs, powered from a high-side voltage up to 220V or 600V respectively. The drivers are highly integrated, with high-side and low-side 5V linear regulators (LDOs), a high-side bootstrap diode, and protection including under-voltage lock-out (UVLO), in a compact QFN package. An integrated fast-startup voltage regulator stabilizes the supply voltage for the driver output stage, ensuring consistent gate control, while an embedded comparator turns off both GaNs on detecting overcurrent. Smart shutdown (SmartSD) automatically holds the switches off long enough to cool down and a fault pin provides overcurrent, overtemperature and UVLO reporting.The drivers are featured to
